3.5 stars - It's well worth the price. But...

The price was fantastic compared for a replacement from Dell. It's $80-$90 less. For that it deserves a 5 star. However, the Dell battery stays charged nearly all day in most cases unless I streamed a lot of video. The BTExpert only stays charged 6-8 hours, sometimes less. That's why i  only give it a 3.5 stars.

Maybe 3.5 stars....
This was an impulse pre-Christmas purchase from another vendor when the price was $54.  I hadn't investigated other bands much at all, other than a cursory look at fitbit (which at the time was only iOS compatible, and expensive).  I didn't even check before purchase that my LG Lucid 3 would work (it does, mostly).  Now, I've looked at reviews of many other bands, and so far I'm glad I got this one.

What I like:  1) it seems to track steps, miles, and minutes fairly accurately - although I haven't checked it carefully against another device; I compare each day to the last,  myself to myself, and it does stimulate me to be more active;  2) it is easy to set up on my phone, and the app is easy to use and gives ok information; 3) it gives me the notifications that I want - I started out using it for all available notifications and it was buzzing all the time - TMI for me, but I have honed it down to the ones I feel I need; 4) it has a vibrating alarm function, fully customizable, anytime throughout the day; 5) the clasp holds well, plus they give you a security band just in case (watch the video for how to "break in" the clasp and band); 6) the online videos were very helpful in learning the idiosyncracies of the device; 6) it's a watch too;  7) it is almost small enough for my fairly small wrists - it still sticks out a bit at each side; I keep it fairly loose on my wrist anyway because keeping anything tight on my wrist is irritating.

What is so-so:  1) Calorie count is way off - it doesn't seem to take into account the daily amount used for just living/breathing and only gives the amount related to the exercise - this isn't really important to me though; 2) sleep has to be set by user and doesn't give any "quality" of sleep measurements (that I've found anyway) - I don't use it because I know when I've slept well or not well by how I feel in the morning; 3) it periodically disconnects from my phone and reconnecting is a challenge - the third time it happened I didn't think it would reconnect, but it finally did several hours later - from reading about other bands and syncing, this might be more of a phone issue than with the device; 4) there's a learning curve on how to tap it to turn on the display - I have found that tapping it from the side works best; 5) it turns on when you shake your hands or bump it, which I'm sure leads to the fairly poor battery life; 5) fairly poor battery life - have had to charge at least every 3 days, more often when it was notifying me about everything under the sun; but it does charge quickly (1.5 hrs); 6) no computer syncing or app, yet at least.

All in all I like this band, and I'm glad I got it, and that it was only $54.  I doubt I would have gotten one for much more money.

Mixed bag but good overall and well worth the price given the length etc.

This item has a lot a good things going for it:
  a.  Good sound for price.
  b.  Remote works great.
  c.  Basically feature rich.
  d.  IPOD works great with it.

It has a few items though that are hard to live with:
  a.  Even at dimmest level, the light is very disturbing in a dark room used for  sleeping.  Instead of backlite LCD, this would be a much better unit if it came instead with a red LED readout with auto dimming.
  b.  The radio tuner seems a little weak in reception.
  c.  This unit is not very user friendly, and I am a techy

Is it worth the money?  Probably yes, but the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Emerson-iC172-iPod-Dock-Alarm-Clock-Radio/dp/B0013ANW9C/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Emerson iC172 iPod Dock Alarm Clock Radio</a>might be a better buy.  Or at least worth looking at.

This is a great player for the price, it works and sounds great, and that is all that matters, right?

I totally agree, but there are a few problems that kill this little MP3/WMA player's glory.

All have been mentioned so far, and I am pretty sure that everyone is aware but now, but why not put my two cents in it?

-I like the fact that you have an arm band and a belt clip. There is a rubberised enclosure for the player that facilitates the mounting to the arm band. My problem is the player's unusual shape causes it to stick out like a sore thumb on the side of your arm. I suggest increased awareness in situations in the gym where there is a possibility of rubbing, as the buttons on the player are akward and stick out.

-Since we are on the topic of buttons, I have read several reviews of individual's players losing button functuality over time. I do not doubt this from feeling the shoddy construction of the buttons. The lock function is also buried too deep down in the menus.

-Speaking of menus, common functions are buried deep and make it a pain, especially when the rubber casing is on, it makes the top buttons hard to access, including volume.

-Music still sounds nice at max volume, included earbuds are good, but may not quite reach some waists.

-Complaints about radio reception; I have not tried it myself, but Rio claims to have solved these problems with the latest firmware update.

-It makes a difference, you will notice the differences in the menu format.

-The software sucks, use anything but the Music Manager. It does work in terms of basic functionality though. The USB cable is proprietary, and Rio states on their website that they have tested SD media up to 1 GB.

-Battery life is adequate, as advertised.

-The screen shows a lot for something in its price range, maybe a little too much, although the LCD does look a little archaic. I will expand on this in the next bullet.

-The LCD screen is the Achilles Heel of this player in terms of durability. Two weeks after I got this thing from Overstock, I clipped it on my Interceptor body armour in an ammo pouch, and took it on an 8 mile ruck march. At the end, I forgot and threw my armour in the back of a truck. When I got back the screen was done. It will take a fall anywhere, but once the screen gets hit, it is done.

In summary, this rocks if you can get it for 30 bucks, it is expandable to 1 GB, but you have to be cognisant of your surroundings, or you will break this toy.

The good: Overall, this is a good product, giving a good price/feature ratio. I have no complaints about the sound quality (though I am no Audiophile, so that may not mean much), and at the end of the day that is the most important thing. That said, I do have a few issues. The first being that the volume adjustment is flaky. Turn the knob on the front of the unit slowly, and the volume will "bounce" around the current value. Turn it more quickly, and it will suddenly adjust very quickly. This makes it difficult to make relatively small adjustments to the volume, as it will keep jumping over the desired value. The effect is less severe when adjusting using the remote, but still noticeable.

Secondly, the Airplay implementation has issues, especially when used in conjunction with the latest Apple software updates. Don't get me wrong: most of the time it works fine. However, I have found that under certain conditions/tracks, it doesn't work at all - in fact, attempting to play certain tracks will cause the network interface on the unit to reset momentarily. And tech support refuses to even *try* to reproduce the issue, even though I offered to send them one of the problematic files to test with, leaving no way to know if this is just a problem with my unit or a border implementation issue.

If you aren't planning to use Airplay directly however, this could be a very good option - though at this point you probably want to get a newer model anyway.

For the record, this is much closer to 5 stars than 4, but in a 4 out 5 system, anything that implies a 10/10 feels misleading. This isn't the perfect keyboard (I've already had to backspace twice simply because the space bar takes so much force to activate), but for the price point, it isn't certainly a nice offering.

I bought this keyboard because I bought the Redragon Perdition Mouse (a wonderful product I've been using for some time now without issue or complaint, could not recommend it higher for the price point). It doesn't quite live up to the mouse, but it isn't a terrible keyboard by any means.

The matte feel of the keyboard is very nice compared to the hard gloss a lot of keyboards use. The keys are fairly close together -- a plus for me as a gamer, as I have access to my F keys with very little effort on my part.

The function keys (music, sound, stop, play/pause) are what they are -- the only one I ever really use is calculator since it's much easier than navigating the windows start menu to get it.

The backlighting is pretty good on most of the keys, however on the longer keys (spacebar, backspace) there's noticeable outages in brightness, which gives the keyboard a cheap appearance. It's hard to knock it too much, however, as they do sufficiently light the keys for use in pitch-black conditions.

The keys are nice and fairly quiet -- no one has complained about me typing while in Skype on this bad boy, which I am sure is a relief for my friends and guildmates.

Finally, we get to the single biggest drawback of this keyboard -- the keys. The keys themselves take a HUGE amount of force to activate compared to many other keyboards I've used (ranging from cheap, $10 HP keyboards to low-end mechanical keyboards) -- it often leads to me making typos and a lot of finger fatigue when it comes to working on writing intensive projects (even this review has been somewhat strenuous compared to my previous keyboards).It hasn't been a problem in terms of actual gameplay (League of Legends, for example, hasn't ever doubted my key presses), and there's enough feedback that you know when the key activates -- it just takes more force than I would like for the keys to activate in the first place.

For the low price point of this keyboard, it's hard to complain too much -- but don't get me wrong, you'll absolutely be aware of the price point while using this keyboard. You're never going to dupe yourself into thinking you bought a beautiful, brown cherry MX mechanical keyboard, but it'll definitely beat out many of its peers in the $20 range, especially for something backlit.

Just got this system connected and, while not perfect, it is impressive.  I give it a strong 3.5/weak 4 stars.  Fact is, you cannot expect a 'one size fits all' component to be perfect in handling nuances between styles of music.  The only way to accomplish that, frankly, is with a separate equalizer.  I haven't yet tried a third party app for the iPhone to do any equalization, but since I accept the imperfection of a one-box system, I'm really not disappointed.  The KMC 3 handles mid-range and tweeter audio adequately for most, though it is stellar for some and mediocre for others.  The bass, however, is amazing for a box of this size and is above standard in response and in comparison to other systems of comparable price.

To be sure, I am a Bose fan and have several Bose portable sound systems.  I have no complaints about those, but I am a Klipsch fan from way back and wanted something with a bit more 'oomph' for my shop.  The Klipsch delivers.  I was able to get a decent sub-$200 deal on the KMC 3, so I would say for that price, the sound reproduction is worth the cost.  Not sure I would be so benevolent at $300+, however.

Pros:

Compact design
Ease of connection to Bluetooth enabled device
Incredible bass response
Dual voltage (only an issue overseas)

Cons:
D cell batteries?  Really?
Sound can get a bit muddy with increased volume...a factor of the bass overpowering the mids and highs, I think.
Very limited range with the remote
(nit pick) No tactile controls (not a fan of flush-mount, touch-sensitive controls)

So far, big band, Van Halen, April Wine, Pink Floyd and Robin Trower are reproduced faithfully and well, if not incredibly well.  Now, on to Zep...the true measure of any audio system!

UPDATE: 8 February 2015

Bought a second system for the house.  The white KMC 3 was discounted to $170 at my local store and, at that price, it's WELL worth the cost.  I enjoy the sound produced by this device and have now test driven it with all forms of music to which I listen.  Again, if you can find it at this price point, and can get past the idiocy of D cell batteries for portability, it's a great bargain.

Ok, first of all, this bag gets a solid 4.7 out of 5 stars. I knocked it .1 to .2 star for some small things. First the good:

1) The strap is seat belt material, but the finest I have ever seen. very tight weave and silky smooth. I have a Mercedes S-class and this thing has better seatbelts than my car (not as big of course.)

2) The zippers have full covers. I very rarely see this design, but MAN was I impressed with this. See the pics. When the zipper is closed, you can NOT see the zipper at all. That is true attention to detail.

3) The interior broad side padding is about as good as it gets for protection. The bumps add extra protection in addition to standard padding.

Now the nitpicks:

1) The bottom padding doesn't go all the way to the center. See the pics for what I am talking about. Now, this setup is probably fine for a thicker 13" laptop, but I bought an Acer S7, one of the very thinnest laptops you can buy. This is on par with a Macbook air. While my laptop does fit snugly in that groove at the bottom, I don't think it is supposed to. I did put the bag down kind of hard on a table and definitely heard the laptop hit pretty hard as there is only the outer and inner layer of fabric protecting the laptop. This is fine for anything but a drop, but a good drop onto concrete directly on the bottom of the bag could easily damage an ultra-thin laptop. I would have paid an extra $2 to get the extra padding at the bottom. But fortunately, this is an easy fix. I will probably just roll up a piece of old tee shirt, tie off the ends and glue it into the bottom and add the padding that way. If this was not fixable, I would have knocked this a full star. This was a major oversight in the design. But again, this applies to only the very thinnest laptops. If you have a thicker one, you should be fine.

2) The front zipper pouch is not quite big enough. I knocked it another .2 star for the fact that the front zipper pouch could (and should) have been nearly the full width of the bag. They might have done this for aesthetics or cost reasons (which I understand), but the pouch could have been a full 2" wider. That is a lot considering the front pouch is 11" at the outside as is. It is big enough for my charger, which is about the smallest charger for a windows laptop you can get. A full-sized laptop charger would leave little extra room in the pouch for something like a mouse. Again, I would have paid another $2-3 for a bigger front pouch. Maybe a "plus" version? It does have an additional back pouch for a thin-to-medium book or USB number pad if you use those.

In conclusion, I don't think you could find a better laptop bag without spending at least 4x as much. If not for the very small nitpicks, this would be an absolutely perfect laptop bag. Asking perfection is a lot these days. But taking the price into consideration, this is my go-to laptop bag, period.

The other reviews have this pretty well covered but I have a couple things to reiterate and add:

Good
1. High quality construction with the single (probably minor) exception that holding it one-handed in your left hand results in some scary cracking sounds.
2. Value - This AMD quad core is solidly near a Core i5 in performance at a Core i3 price.
3. Battery life - I haven't run actual tests like playing DVDs on battery, but it's definitely better than I expected at this price with this battery.  I suspect it's due to power improvements in the CPU/GPU, screen, etc.  I'm getting 5 hours easy of mixed usage.

Bad
1. Keyboard - I can't stand the chiclet keyboard.  Maybe I psyched myself out because I thought it might be a problem, but it's been 3 weeks and I'm still having a really hard time getting used to it.  Read the other reviews though because it looks like I may be the anomaly.
2. Touch pad - Nice touch pad, but it's some type of multi-touch and I'm constantly resizing things on my screen by accident.  I'm sure it can be turned off but I haven't found it.
3.  Screen - This LED screen has good brightness, but to me it's blurry compared to a traditional (LCD?) laptop screen.

Summary - I almost gave it 3 stars because the keyboard annoys me so badly and it took me twice as long to type this review as it should.  However, for someone else, this is easily a 4-star laptop.

Edit: Updating to five stars. If I could do 9/10, I would. This little unit is very highly featured and has great sound quality.

Currently there is one other review for two stars of the Pioneer AVH-X2800BS. I guess the marketing nerds at Pioneer don't know you shouldn't put "BS" in your product names, I digress.

The issues our other reviewer has had with connecting the phone into the unit wirelessly, I am not experiencing.

The good:
Four stars for value, features, and sound quality. I paid $245. This unit has a DVD player, video in/out, a separate reverse cam-in (more on that later), built-in high and low pass filtering with selectable slope for front/rear and sub RCA (4 volt) outputs, and plenty of power for stock speakers. The sound quality, is a clean sounding unit free of amplifier distortion/clipping up to the max volume. I purchased and installed an eSky back-up camera too use with this unit, and as long as you wire it all up correctly, the backup feed comes on automatically. A huge benefit in my full size truck. The integration with my Galaxy Note 4 phone book/contacts is well executed, and hands free calling is a breeze with the included wired microphone.

The bad:
I could have given this little dynamo five stars if not for one thing. My major gripe is that the unit is not quiet at idle, leaking high frequency noise when powered up without an audio signal. I usually associate this with poor filtering of the display noise from the audio section of the unit. That's my layman's way of explaining the issue, I'm not sure that's exactly what's causing the noise. As an audiophile, and based on my long term positive experiences with Pioneer car audio products, this is disappointing. Fortunately, this "threshold" noise doesn't increase in volume with increasing volume levels. Basically, as long as you're using the unit, or driving down the road, you'll probably never notice this.

The ugly:
There are minor quirky things with the Bluetooth connection, along the lines of the text displayed, the time signal for audio processing seems to vary a bit (audio playback slows and speeds up seemingly at random- the BT Audio in my Subaru legacy does the same thing, it might be my phone), the "mode" button on the unit face doesn't seem to do anything at all.

The thing is, were talking about an extraordinarily feature packed multimedia computer that is expected to play nice across multiple software and hardware formats, and it does an exceptional job of that considering how little retail is on it.

Would buy again, no hesitation.

This unit is pretty decent. It works well, it's virtually silent, and as soon as you turn it on you'll see a big plume of vapor rising from it. It really does noticeably help during dry periods.

There are some downsides:
* The blue light is not UV, there is nothing to kill bacteria so you should change the water often

* The fountain of vapor, although blown upwards by an internal fan, will fall around the base of the unit. I've never really had any problem with water collecting, but still, don't stand the unit on a material that might harbor mold or be sensitive to moisture.

* There is no timer or automatic shut-off if the humidity gets too high, so unfortunately you can't really feel comfortable going to sleep with it on.

All in all it does its job well for the price. Unfortunately my unit after only light periodical use has started having some problems. Particularly, the materials around the "energy exchanger", which is essentially the part that produces the ultrasonics, seem to be warping and deteriorating. Nevertheless, it's still working for now. I don't rate it down too harshly for this because after reading most of the other reviews for humidifiers of any kind on Amazon it does seem that no matter what kind you buy they all need regular maintenance and they'll all degrade over time in one way or another. At this price point I figure I can afford to buy a new one each year if I have to without hurting my wallet too harshly.

My biggest gripe is with Air & Water, who at the time I purchased charged an extortionate amount (about half the price of the unit!) for what turned out to be 2 day shipping. That left a very sour taste in my mouth. Moral of the story: if you need the unit fast check what kind of shipping you're actually paying for - "expedited" might not be as fast as the cost leads you to believe.

-----

Update:
I'd actually like to warn everyone out there about ultrasonic humidifiers. I've recently discovered that they kick out *huge* amounts of fine particle pollution into the air. I discovered this after my air purifier went nuts every time this humidifier was running. Sure enough, when I whipped out my green laser pen I could see zillions of fine particles flying through the beam every time this humidifier was running. I switched to a warm mist humidifier (which boils/evaporates water) and have no such problem.

Upon further research I found science articles stating that ultrasonics can inject so much particle matter into the air that they can bring the air quality below EPA standards for breathable air.

I've seen others on Amazon comment on "white powder" being dispersed by these things, and I always thought they were crazy. I guess not! I didn't actually notice dust around my room (maybe the water quality is good where I live), but I did notice quite a volume of it collected during vacuuming after running the humidifier for a week or so.

I now strongly recommend against ultrasonic humidifiers altogether, especially for anyone with asthma or other respiratory issues.

First off, the headset is only $20 if purchased with a Sony Ericsson T610.  For that much, this is a must buy.
The concept is wonderful, and it works well for the most part.  I can speak wirelessly with my phone elsewhere.  The headset itself is comfortable - especially the eargel.  It fits snugly and sound is clear.
Two gripes, however:
1) Battery life is less than impressive.  Jabra claims 3 hrs.  I have yet to get beyond 2.  In fact, last night when I used it, I got a warning signal at exactly 1:51.
2) Bluetooth range is 30 feet only when in a clear path.  My bathroom is 15 feet away.  I get noticeable static on my end.  If I close the door, everything becomes unintelligble.  The interesting thing is that the person on the other end doesn't seem to notice a thing.
All in all, it's a great concept and works well aside from the two gripes listed above.  I recommend it.

I am a 5 star fan of this unit, however there are a number of things that sort of need to be considered.

While the unit touts the ability to install 8+ drives, it isn't 'that easy'. Mounting 2.5" drives directly on the chassis has issues with clearance of SATA cables. I'm also a bit concerned with mounting of 2.5" on the external faceplate. That plastic on metal doesn't thrill me. There is also a need for a few more of the 3.5" mounting screws than they supply if you want to do anything clever - a bit frustrating really.

Some items that made this 8 x 3.5", 1 x 2.5", 2 x SSD install happen:

What Fractal does wrong here is provide some trivial fan control, a manual switch to regulate H-M-L based on voltage. It is a waste, no one (relatively) will use it. Not enough of an annoyance to cost a star though.

Also some thought in a backplane (even if an optional purchase) would be useful for those hanging drives. Getting SATA and power to them in a clean, neat and manner that does not cause cable stress wasn't nearly as easy as I had hoped.

The product does lose a star for lack of sound dampening. While not easy to keep 8 spinning drives quiet, it seems the construction of the unit with it's many cutouts simply fails here. For a device that may function as a hybrid HTPC / NAS, this is important.

It's worth it. There is a little bit of constant feedback that interrupts the music, but it's not that noticeable.

Beautiful guitar which has elicited many kudos.  Nice sound that reflects whatever strings are placed on the guitar.  Five stars for both of those qualities.  Lower score for not containing one strap button (meaning either you have to drill into the hardware or buy a different strap for such guitar setups.)  Guitar was set up nicely out of the box, though.  Sounds great, and the tuner is still working, which is key.  Electronics currently work, which is nice.  We'll see how long it lasts, though.  3 Stars.  Would buy again, but would prefer proper strapping.  Also, beware - the center hole is smaller, and, therefore, you will damage your guitar by placing a rubber stopper in it for amplified use.  I tried to place one inside the hole, and heard a slight implication of "cracking" and therefore stopped attempting to fit it in.  No visible damage, though, but I had to buy a "special fit" from "Lute Hole" for over $50.  Their prices for noise blockers are ridiculous (a matching one would have set me back over $100, so I went with an unmatching item and repainted it), but I haven't seen any others that custom fit.  Not great.

I bought mine through eBay because I didn't expect Amazon to have such a great price, but I paid only a few dollars cheaper and got a free bike handle mount, which I don't even use. Anyhow, I'm writing this review to explain why it's not a 5-star. The headphone port is a *2.5mm* NOT the standard headphone/mic jack of 3.5. I bought a mic and now I have to get an adapter because the 3.5mm plug doesn't fit. I didn't see anywhere that it was a 2.5mm jack, just that it had an external microphone port. Other than that major feature that has irritated me enough to leave this review, the camera is impressive. I love that the software shows you live feedback of the entire trip on a map, as well as your speed. It's got a great auto white balance and the dark to light/ light to dark exposure transition. Since Contour's business is all up in the air right now, most of their mounts are sold out. I would liked to have seen 2 of each sticky mounts included. After applying a mount and then seeing the video, I see I needed to make adjustments, but it's too late.
