Don't give up on this - it's a very nice device

First of all, I vacillated between giving this a 4 or 5 star rating.  It works great and is exactly what I was hoping for.  The ONLY reason I didn't give it a 5-star rating is because it took a little bit of "playing around" and user guide reading to optimize it for my TV.  I am using a Windows 7 Professional Lenovo B360 notebook with a Windows Experience Index of 3.9.  Diamond's minimum requirement is for at least a 3.0.
So, let's look at the installation procedure.  If you have Windows 7, throw away the booklet that came with the device and follow these steps.  Connect the included HDMI cable from the WPCTVPRO to your TV.  Connect the power cord.  Turn on your computer and plug in the USB transmitter.  Be patient while Windows detects the device, downloads, and installs the driver.  Follow the prompts for installation.  When finished, you're all done with the installation and you now have your desktop displaying on your TV!  That gets a 5+ star rating for ease.
Now comes the optimizing it for your TV part.  In my case, when I first viewed the display, my first impression was, "Oh no!"  The desktop doesnt fill the screen, but occupies a rectangle filling about 3/4 of the screen.  For those in the same situation, relax, this can be corrected.  Now, it would be nice if Diamond had been more obvious that you really needed to read the DisplayLink User Manual to set up the device for your situation and that there is a DisplayLink configuration utility icon in the System Tray, ONLY when all components are connected and on.  OK, two things have to be accomplished now.
First, the reason you aren't getting a full screen TV display is because your computer doesn't have enough "Oomph" to run both displays.  So you have to switch from the default "Mirror" mode to displaying on the TV, only.  This can be selected from the configuration utility.  This immediately fixes the full screen problem.  If you have a more powerful computer, you can probably display both screens properly and don't have to worry about this step.
Next, you may find, like I did, that the display doesn't properly fit the screen.  The top and sides of the desktop screen were beyond the TV dimensions so I couldn't see all of my menus, e.g., the "File" toolbar menu in Internet Explorer was not visible, nor was the "X" to close the browser.  To fix this, while displaying on the TV, only, and using the DisplayLink configuration utility (in the system tray), click the "Fit to screen" option.  All I can say here is to use the + and - adjustments to get the screen to fit.  If you're like me, it will take some trial and error to see exactly where you are in screen size when making those adjustments, but eventually, youll have the display set properly.
Youre now finished.  You should have a full-screen display on ONLY the TV and the desktop should fit completely and perfectly on the TV screen.  The last thing is to set the configuration utility for Optimize for Video when displaying video content  turn it off, otherwise.  This procedure gets a rating of 3.5 stars because it works, but it isn't obvious that all this has to be done.  And, depending on your computer, it may not have to be done.
There are a slew of other adjustments that can be made and they are described in the user manual.  I haven't read the whole manual, just enough to get it working to my liking.
Last step, sit back start a video on your computer and watch a very good computer display on your TV.  This gets a 5-star rating.  A very nice device once it is set up.  Dont give up on it.

This is an all around great device. The processing speed is satisfactory It plays music louder than you would expect, with the sound quality still being clear. The screen resolution is great.
The touch sensitivity is not that great at first but you get used to it and it gradually stops being an issue at all. Also the advertised 8GB of data is somewhat false. I whole 4GB of data is system data. But 4GB of data is more than enough for me personally.

This is a very cool little machine. I followed J. Chung's great instructions (in his review) to upgrade it to 6GB of RAM (using&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/this-Crucial-part/dp/B005LDLV6S/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">this Crucial part</a>) and a 128MB drive (using&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/this-Transcend-unit/dp/B00KLTPUU0/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">this Transcend unit</a>). I have also upgraded it to Windows 10. I'm very happy with the purchase for my use-case which is to hang it as yet another "streaming" device off my TV. (I also purchased&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/a-Logitech-Living-Room-keyboard/dp/B005DKZTMG/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">a Logitech 'Living Room' keyboard</a>&nbsp;to facilitate using it from the couch. I stream videos or music content accessible only via a browser as well as run some Win10 apps on my big screen. Slick, so far quite stable, and remarkably general purpose; perfect for "filling in the hole" left by my TiVo and my Fire TV.

I'm very happy with this product. I happen to agree who said this is a friend of his. Very useful device.

I ordered this item on December 14, 2014 and got it 13 or 14 days later. Came in a neat, sturdy little box while the device itself was encased in another box made of firm plastic. It appeared as it does in the pictures shown; however, after having it for almost two months and have only used it maybe a little over a handful of times It would seem that I'm missing the top screen that seemingly dims the light. I have no idea where it's gone, but where you see the black outline in the pictures (like the black outline between the green at the top and bottom of the screen) is white for me - and kinda freaks me out for some reason. I really wish I could post a picture. It still works perfectly; the audio is wonderful; and the battery life is fantastic. The controls are something I have to relearn, which after some fumbling I'll have down soon enough. I love the fact that you can make folders of music depending on your preference, and adding music is as simple as drag-and-drop - though I think it took me some time to get it to actually find my music on my PC. I've learned during my quest for a new MP device that a lot of these players won't allow folder creation and will make you scroll through ALL of the songs added just to get to one and will start you over from the very beginning of the list when shut off. Absolutely not down with that, so even though it's missing its screen and took roughly two weeks to get to me I'm still very content with my purchase. Also, I found the exact MP3/4 Player in a claw game at Pilot Flying J (Travel Center?). Depending on your skills with that kind of game, you could probably get a 2 or 4GB player for a dollar.

Update (11/11/15)
I'm still content with my player and found the missing black screen; however, I'm rather displeased that I can not add any new music to this device from my computer for whatever reason. Instead of a little window popping up to access files when I plug it into my computer, nothing comes up and will only charge. For $13.98, it's an alright deal if you're not planning to update any of your music....ever. I'll try using it with another computer in the future, tho I shouldn't have to.

I was thinking of buying an Apple iPod, as the new ones are pretty, but I heartily object to Apple's treating me like a thief (mp3 names scrambled) and not letting me use the player as storage as well.  Also, the idea of an SD slot seemed extremely useful.  I've had good luck with Creative sound cards and read many positive reviews here, so I decided to buy this little gadget.

While not an audiophile, I do a lot of music production and studio work and have to say I prefer the sound from the Creative Zen X-Fi to my friend's iPod for the same headphones and sound file.  It seems less fuzzy somehow- I think they must be doing something with the EQ?

My issues are as follows:
-Creative Centrale is not very good software.  It keeps track of my iTunes library very well in terms of tracks, but it's terrible for importing playlists.
-Creating and editing a playlist on the device is difficult to figure out.
-I wish I could play all the songs by one artist.  Will see if firmware upgrades ever do that.

I admit I haven't tried anything with video or pictures.  Charging is the same as any other USB device, and I'm really glad I don't need to use a proprietary connector (like Apple uses) or dock to charge it from my computer- my camera cable or cell phone cable both work for this, since they're all mini-to-USB.  Have not tried the voice recording.

I managed to crash it once (no batteries plus connecting it to a non-charging source), but rebooting as it tells me to on the Creative support site fixed the problem.  The speaker's sound quality was a nice surprise.  As for the controls, they weren't difficult after reading through the quickstart guide once.  I'm also pleased by the ability to delete files from the device without connecting it to a computer.  However, I couldn't get the device to work with Linux.  I don't think most users would even contemplate that, though.

I hear that the SD card content is not integrated into the player's library, which means I'll have to store my less-used movies and music there when it comes time.  But the functionality is amazing, the sound quality lovely and crisp, and the ability to manage my own files means this one's a keeper and I recommend it to all who want to be 'power users' of their portable devices.

I bought this about a week ago and still haven't decided if I'm keeping it (it's really great, when it works properly).  So far I haven't been able to go for one day without having to plug in another keyboard / mouse for when I can't reconnect the diNovo.

Let me recount the fun I've had with this:

I took it out of the package and was pleasantly surprised with how it looked and how it was packed; all scratchable surfaces were nicely protected with pronottective plastic backing.  I plugged in the hub and used the keyboard with a wired mouse while the included mouse was charging (took about 4 hours).  It worked fine without any drivers (except the media pad obviously didn't do anything fancy).

Then the mouse finished charging. It too worked without the drivers.  Then I installed the drivers, and the fun began.

During the install I was prompted to update (and an insert in the package said it was very important to do so).  After rebooting, I was greeted with a crash while the software finished setting up the hardware; this left the keyboard and mouse unusable; I used another kb/mouse to uninstall the drivers and tried again.  To make a very long story short, I started at 10 PM and finished at 6 AM, installed a half dozen times on two different computers, and finally got it working.  During the post-install (after rebooting) a firmware upgrade is applied (this is what kept crashing); I suspect it stupidly hard-codes c:\program files\ because on another installation on the same machine (which also happened to use d:\program files) it kept crashing, but on another machine with c:\program files the firmware upgrade was successful (and then it didn't need to do it again, so it worked on the original machine).

Often all three pieces (kb/mouse/mediapad) lose their setpoint detection and stop doing their special functions (e.g. F-lock/media keys, cruise control and tilt scrolling, and the media display stops updating).  I can reconnect the devices and then they work properly again.  Sometimes they don't reconnect and then I can't do anything because I lack a keyboard or mouse (and often when trying to reconnect, setpoint causes winamp and explorer to hang).  I have found that restarting setpoint also redetects the devices sometimes.

Long story short, the software is a mess, be wary.

Very well functioning device once you get it working.  The instruction out of the gate didn't work for me, but the direct connect method to my laptop for setup worked flawlessly.  Once setup it works great.  Be patient, as it takes 30 seconds to a minute for it to reset once plugged back into power.

The lag isn't bad and the bandwidth is pretty good.

Definitely recommend this one as it allows you to plug in another powered device

Most device like this I have had back luck with. This one actually works, and does what it says

I was provided this device as part of the friends family program for free.

I am tired of seeing reviews by people who don't own the device. Keep your opinions to yourself, there are people who want to know the read deal because they are considering a purchase. I had to wade through lots of crap to find useful reviews here. I wish Amazon would delete all reviews from people who haven't purchased the device and I think you would see a much different overall rating.

Well I own the device. It rocks! It's an awesome device.

I purchased the device to be up-to-date on my newspapers and blogs. I find the experience to be better than I expected it to be.

The screen looks awesome and the scroll wheel is much much better than I expected. The buttons and keyboard work great.

To be honest I expected pretty low quality keyboard and buttons after seeing the first photos of the device. However, I am very happy with it.

The items are delivered very fast to the device. I purchased the NY Times, WSJ, TechCrunch, Scobelizer and some others before the device arrived. Using the manage features of Amazon.com.

When the device arrived, it was shrink wrapped in plastic and it's a white book looking box, surrounded with typical Amazon packaging and brown box protective shipping. I opened the device and the first thing it said was to charge the device, so I plugged it in and turned it on. I left the device for about 2 hours (as recommended).

When I came back I started using it. The screen needs to be in a lighted area, however I have noticed that it works good in not so lighted areas if you increase the font size. I am super happy with the scroll wheel. I thought I would suck, but I think it's pretty cool after using it. It has this nice metallic look to it when it scrolls.

I added a 2 Gig SD card to the device. It ships with 256 MB memory, I assume onboard flash, but I have all kinds of devices and crap laying around so I put in one of those SD cards to make it have more memory. Unfortunately my SD was formatted NTFS, so I had to reformat to FAT32 so I had to remove the back cover twice (stupid user mistake). But it only took a few minutes to do.

There are some very cool features on the device like listening to MP3s while you read your ebook and a built in web browser using EVDO. Both of these features are listed in the experimental menu. I guess Amazon is eating the cost of EVDO for me to web surf at the moment, not sure how that feature will progress into the future. I find it pretty appealing. I am also getting pretty fast speeds on the web browser, I also have 5 bars on my EVDO connection, that might have something to do with it.

I currently have Sprint EVDO PCMCIA card for my laptop and contrary to opinion I have read, it works great. I travel all around the USA and it works everywhere I go.

This thing is pretty cool, but I've had several technical problems with it that make it very difficult for me to rate it higher than a 3. =(

First, the good.

+Looks great.  The physical styling of it is very cool and the screen is beautiful as well.

+Battery life is LOOOOOONNNNGGG.  I think I've only ever had this thing die on me once or twice.  Battery life is an important factor for me because I listen to higher bitrate songs than most people, so a "10 hour battery life" is only about 5 or less for me.  This thing boasts a 40 hour battery life, which means I get 15-20 hours of use out of it which is just great.

+Sound quality is pretty sweet too.  It has a True Bass feature which really enhances the bass sound of the songs.  It *really* sounds great.

+Lots of space.  At 16GB (14.4 GB, actually.  I don't know why they say 16GB.  It's inaccurate.) I can hold a lot of songs.

+Voice recording feature so you narcissists (like me) can record your own voice logs and listen to that sweet, majestic sounds over and over.  Or, you can use it to record lecture or interviews as well.

Anyways, that's the good.  Now for the bad. =(

-I've had a lot of small technical problems with it that really irritate me.  I've had it freeze on a couple occasions and sometimes it'll take several minutes to just start up.  Also, sometimes while listening to music it'll randomly make this strange buzzing noise for a second.  Reliability is a major factor for me, and while these problems aren't prohibitively frequent, they still bring down my faith in the reliability of the product.

-Uploading files to this thing via the included cable takes FOREVER!

-I don't like the navigation on this thing.  I have all of my songs organized in folders according to subcategories, artists, and albums.  I'd like to be able to listen THROUGH folders.  As in, after I finish with one folder, I'd like to move on to the next, but it does do that.  This make it very hazardous for me to navigate to a new song on this thing while I'm driving.  In contrast, with previous MP3 players I've owned I could just press the "next" button a bunch of times to get to the next song.

Unfortunately I can't fully recommend it.  There's just no REASON to get it aside from battery life and storage space.  However, those are two HUGE factors in MP3 players and they do warrant a purchase.  So, I'd say it's worth it for those reasons alone.  But if you have an MP3 player with a lower *listed* battery life and have had no problems with that, then the additional battery life in this thing is meaningless.  And if you don't have a need for a lot of songs, then this is also useless.  With those two factors gone, I see no reason for this product.

Alternatives to this product include the Sansa mp3 players (MiniClip, Fuze).  Those have slots for microSD card (I think it was that) that enable for MASSIVE storage space for little cost.  Their battery life isn't nearly as good though, however I've never had a problem with my old MiniClip freezing on me or making strange noises; and that accounts for a lot in my book.

When I first saw this product, online at the (...) website, I was impressed by its compact, sleek design - especially that the screen cannot be seen unless it is displaying the track - and many features. As well as an mp3 player and FM radio, it can be used as a memory stick.
The device fulfilled my expectations fairly well. The controls may not be intuitive at first, but after using the device for a few minutes I was able to get the hang of them. Using the NW-E507 as a memory stick is slightly inconvienient because of the long USB cable, but that's not its main function anyway. I am very happy with the device.
However, as many people have mentioned, you must use the Sony SonicStage program to transfer files to it. The SonicStage program is not the best program, but I have seen worse. My main beef with it is that it tries to do too much; if all it was was a utility to transfer songs, I would be fine with it. But no: it's a big program that takes a few seconds to start up and doesn't always do what I want it to do. Also, when I made a playlist to put onto my NW-E507 and transferred it, it transferred all the songs along with it, all of which were already on the player. Most likely, I was just doing something wrong, though. I don't mind the software too much. I'm just glad I don't have to play my music with it.
The other slightly annoying factor is the long USB cord that comes with the player. I always have to have it coiled up on my desk when transferring songs. I suppose I could go out and buy another one, but I'm too lazy.
Anyway, I am overemphasizing the things that annoy me a little, and not writing about the good stuff. It has great sound quality (no thanks to the Sony earphones), and once I get the songs on it, they are easy to find, and they will stay well-organized if I make them that way on SonicStage - not the easiest thing to do. I have just downloaded an update that I hope will allow me to transfer music directly to the NW-E507, and ... AHA! Yes, it does! So never mind all you people worried about the software. You still need to use it to change the names and stuff, but I hope the "MP3 File Manager" makes my life a little easier. (...)

Anyway, so far I have a very good impression of it. Though it may not hold as much as an Ipod, I would much rather have the NW-E507 than an Ipod.

This is such an amazing device. I am so happy with it, and even though it's pretty spendy it has been quite worth it. Thebother models are completely fine, but if you want the closest feel to actually holding and reading a physical book this is hands down the way to go. It's really nice having the physical buttons as well. I would prefer an option that doesn't have real leather. It is nice to be able to take the case off if you want too, but you also are paying the extra cost for it. The moral objection aside it is a really nice combination. It stays charged really well, and the way the device and case just suction to each other makes it easy and convenient. If you love to read, and do it regularly than it is probably worth the extra cost. Otherwise you may not want to spend so much on it. Great device overall.

This is a phenomenal device. Not only does it do everything that i need plus more,  it is very sturdy. About a month after i got it, i accidentally left it in my outside studio, not knowing that it would rain. Well, needless to say, it did.  I ran back home hoping that it didn't get wet. Well, IT DID. It had so much water in it that i had to hold it up and drain it. I was devistated. But, the good ole mpk 25 never missed a beat, i plugged it back up the next day and its still going strong to this day with no problems.
I was brand new to making beats and i knew absolutely nothing on how to get started
 But after playing with it and watching a few tutorials,  i started to see its capabilites and my imagination come to life. I debated on weather or not i should buy the mpk25 for months,  but i don't regret buying it at all, as a matter of fact, i would suggest that you make the purchase,  you won't regret it. I am highly pleased.

This thing is AMAZING and I am kicking myself for not having discovered these gadgets sooner than I did!  Wireless connectivity is relatively reliable 2 rooms away - it matters how many other connected devices are using bandwidth at a given time, however - just like any other wireless device. Netflix and HuluPlus and You-Tube work flawlessly but other, less-popular streaming apps seem less stable and quite glitchy.  Fortunately, there's a work-around for that so it's essentially a non-issue!  This thing is small and doesn't clutter up precious space like a tablet, laptop or computer would - the biggest bonus is that it uses Android apps that aren't available on those other devices yet has all the apps you've grown to love and appreciate on your PC!

Update: April 14, 2015.  I order this device exactly one year ago today.  Up to recently, it worked wonderfully.  I noticed a couple of weeks ago, there was a power "glitch" and I lost all function.  Then, suddenly, I touched something just right and I had function again.  So, for a couple of weeks, it's been business-as-usual and I'm a happy camper.  Until today...another power glitch and I got nothin'.  The difference between a couple of weeks ago and now is that the power's on but I've got no interface and no way to control the device.  It's basically useless with no way to fix it.  For as much as I paid for this thing, I would expect it to last a lot longer than exactly 365 days.  But, I suppose I should count my blessings:  given some of the other reviews I've read, my device has held out quite a bit longer.

I spent 2 days scouring the internet for a resolution to my problem and finally came upon some extremely obscure YouTube video that showed how to do a factory reset on a bricked device.  I followed the instructions and voila - was able to boot it and restore it.  Of course, I lost all of the data I had accrued since I started using it, but that pales in comparison to having a device that doesn't work at all.

Still no response from the Seller with regards to any amount of customer service - just wanted to know if they could help with a fix for the device - I guess not.

I still like this device, but if I wasn't a persistent, semi-tech-savvy kinda person, I would have a piece of useless junk here - and I know that there have been others who have probably encountered this situation who didn't know what to do or where to turn with their issue so they just junked it.  There should be better customer service for the products we purchase - not just here, on Amazon, but ANYWHERE.

I'm very happy with this device. It works perfectly. But getting it up and running was not a cake walk.

The problem with this tracker is that it has a lot of features and each one has its own wire. So, what I did is I took a pair of scissors and I cut off all the wires for all the features I didn't plan to use. That left just two wires--the ones that connect to the battery. If you keep it simple, it works great. If you want to try out all the features, you better be another Steve Wozniak.

This is actually two trackers in one box--GPS and GPRS. Forget about the GPRS, the cell tower triangulation. It's sometimes wildly inaccurate and getting it to work right is complicated and frustrating. The GPS, on the other hand, is very accurate and the set up, with default settings, is simple and works great.

The tracker needs a regular size cell phone SIM. A lot of users get the T-Mobile SIM. I would recommend getting the H2O SIM. It's cheaper. Also, if you get the T-Mobile one, you'll have to put it in a cell phone to read a text message that they'll send you to set up your account. Save money and hassle and just get the H2O SIM.

The instructions aren't the best in the world but if you're setting it up for simple tracking, they're OK.

I installed mine under the hood of my car with duct tape. It does just fine in the heat and it won't drain the battery. My car was sitting for two weeks straight with the tracker turned and it didn't drain the battery so the power consumption must be very low. The two wire antennas it has, for GPS and cell, I strung up under the windshield wipers. That gives it some exposure to the sky and yet it can't be detected.

If I want to know where my car is (people borrow it), all I do is call its cell number on my iPhone. The tracker then sends me a text that says where the car is, how fast it is going, and in what direction. When I tap on the text message, it goes straight to Google Maps and I can see where it is. It's that simple.

I've called the tracker over 100 times and it has received my call and sent me the location 100% of the time. The failure rate is zero. The accuracy of the location is almost always within 20 feet. Not bad.

So I highly recommend this tracker as a device that is rugged, accurate and reliable. But if you want to try out all the bells and whistles, good luck.

I have had my Fuze now for three months and I must say I am very pleased and happy with it. Since purchasing it, the firmware has been upgraded to handle OGG and FLAC. I purchased an 8 gig MicroSD card to expand the total memory to 16 gigs and so far, it has been a wonderful experience to have my entire CD collection (and all other MP3's I've purchased from Amazon) on one device and still have plenty of room to add more.

The sound is excellent with the supplied earbuds that come with it. The unit itself is sleek and compact. Response with scrolling through my long lists has been improved since a firmware upgrade that now allows you to speed up the scrolling based on how fast or slow you spin the wheel. Also, replay gain is available as is a 5-band equalizer with various presets included.

Having the choice between MTP or MSC mode is nice. I prefer the MSC mode so I can drag and drop through Explorer rather than having to use Media Player. Of course, if you have any WMA files (not me) that have DRM, then you'll need to use MTP mode. Since I don't have any DRM files I don't use MTP. When I initially got the player, I found MTP mode did not work very well at times. I use Media Monkey to manage my library and using MSC mode with it is great as I've set it up to look at the Sansa internal and external memory as USB devices. I can then manage the music directly on the Sansa, including tagging and moving/updating/deleting the files.

I only have a few gripes with it but for me, they are not major.

Video playback was a nice "to-have" but as others have said, the screen resolution is pretty small so videos don't have very good resolution. It's neat but not really something to write home about.

Another gripe is that the battery life doesn't seem to last a full day for me without going down to almost 25% (this with me listening to it for about 5 hours at work), but it's not all that big of a deal. I guess that's close to what they say. I use OGGs ripped at 128 but OGGs apparently draw more on power on the battery. I've since switched back to mps3 ripped at 160 and the battery life has increased.

Another gripe is the lack of gapless playback. I have a lot of live albums as well as a lot of techno/trance that are gapless on the CDs. The live CD's aren't that bad when there is a 1 second pause as it switches to the next track, but it definitely affects the techno/trance/dance mixes. For those, I've just ripped them as one huge track. Sansa is apparently working on getting gapless playback, but it's not a HUGE issue for me.

My final gripe is when it does a database refresh. With the large amount of music files I have on it, it sometimes takes a minute or two when I disconnect from the computer. This only happens when I've modified the files in one way or the other (either modifying a tag or adding or removing files). However, once the refresh is done, it doesn't do it again until I've hooked it back up to the PC and modified something.

Overall, for the price, I was able to get something less expensive than the "other" player that satisfies what I want: a durable MP3 player that has enough kick to it without taking a huge chunk out of my wallet.

Not displeased with this purchase in any way at all.
