Good product for $2.83, but not flawless

I love the low profile look and feel of this case, but the 'rubberized' coating wears off very easily. I have not dropped the phone at all, and I'm careful to make sure that I put it in pockets without loose change or my keys. Regardless, there are a number of unsightly spots (particularly along the edges) after ~1 month of usage.

Hard to beat the price tag compared to the $25-30+ you'll probably spend in a corporate store, but it may be worth shelling out a little bit extra for a more durable case.

For the price of this product, you really can't complain. There are much more expensive shutters, and attic vents out there, but for the price you really can't go wrong. Granted, I have only had it installed for 2 weeks, and it's working fine. A Little noisey, but still working. The temp. in the house has dropped, and it's serving the purpose.

As far as installation, it was a breeze. In the application that I needed, with the wiring being run externally. I was able to install the entire assembly in about 2 hours without having to enter the attic. Which, with temps. being in the mid 90's, was a major bonus.

Overall:
Quality 1 star
Usability 2 stars
Functionallity 4 stars
Close enough: 10 stars

I didn't give it 5 stars because it isn't perfect... but for the price, it's pretty darn good.

Installation: Super easy! Familiarity with what's under the hood of your PC helps, but if you can follow simple instructions, you should be good. It takes 2 5.25" drive bays. I only had one bay free, but I'm pretty handy with a dremel and not afraid of a little minor pc-case surgery).

Hardware: YES, the VFD looks washed-out on installation. I'll give you that. BUT the contrast and brightness are software adjustable. So, if you spend a couple of minutes adjusting it, you can get to look like the one in the ad. The remote range and reception angle are quite good for me. The front buttons work fine, but are fairly useless with the remote (pretty much like any home theater appliance).

Software: As someone else said, don't bother with the bundled disk. Just get online and download the latest drivers and apps. I'm using Windows 7 (64bit) and the software works pretty well with it. The ability to turn the computer on and off, and launch your apps by remote control is outstanding. You can configure what apps that launch as well as the remote commands within the apps. I'm using it with Windows Media Center, XBMC, Hulu Desktop and Boxee. Haven't had a problem with any of them so far.

YMMV, but this unit is just what I needed for my HTPC and works really well so far (had it for about 2 weeks).

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.

This is my first bluetooth keyboard for the iPhone 4, and I have to say that overall, I am pleased with this product. It is nice to have a tactile keyboard; I have had iPhones since the first one came out, so I have had years of experience with the virtual keyboard, yet I still find myself endlessly trying to correct typos. The tactile keyboard really cuts down on the number of typos and shortens the time necessary to type a long email. I still use the virtual keyboard for quick texts.

Anyway, the quirks:
First off, the build-quality is not top-notch by any standards. There are some creaks in the plastic, and some of the keys have a double click. After two weeks I started noticing some paint chipping off of the keys. Also, the keyboard, when not exposed, does not sit flush with the case that holds the phone. If you look at the front of the case, the corner with the camera cutout sticks out a bit. The biggest quirk of all, however, is with the capitalization key: for some reason, if I try to type a capital P, after pressing the shift button, the P comes out lowercase, and the next letter in the word is capitalized. I don't know if this is universal with the backlit edition or just on the unit I received, but it is annoying.

I am hoping there will be an update that allows for the auto-correct functionality to remain functional while using the keyboard. I would love auto-cap, and double-spacebar periods.

Overall, however, I am pleased with this product and would recommend it, especially at its sale price.

This is a good product for the price. It's lightweight but feels stable and is very easy to install - just set the height of the shelf and secure it to the underside of your desk with 8 screws. A few things to note, though:

1) I didn't measure my keyboard and mousepad beforehand, so the shelf wasn't as wide as I expected. If you have a full-size (104- or 108-key) keyboard, you most likely will not have room for a full-size mousepad on the tray, hence the mini-mousepad provided. If you're a gamer and need a standard or oversized mousepad or gaming mat and also have a full-sized keyboard, definitely buy a wider tray.

2) The supplied mousepad is very flimsy and thin. Luckily, it's removable, and mousepads are cheap. The wrist rest is actually decent, but can also be removed or replaced.

3) The 8 screws provided are ok, but if you want a more secure hold, I'd highly recommend using wood screws to attach the tray to your desk. Depending on what your desk is made of, you may want to drill lead holes beforehand.

Also, while it's possible to install this alone, it helps to have a second person hold the tray in place while you're making marks for screw holes and screwing it in.

Been using this unit a few weeks now. I didn't need the VGA part -- I only wanted a two-port USB switch for my mouse & keyboard and this was the most reasonably-priced item I could find that would fit the bill.
  The good: works perfectly fine without any VGA connectors attached to monitors, so works for my purposes just fine.
  The bad: Well, the cables that come with it are a little bit short. I have two computers each at opposite ends of a cafeteria table and the cables are basically not long enough to reach both of them (not and still have the unit be on the table instead of on the floor.)
  The nit-picky: It takes about 3 seconds for the unit to switch over between computers. It would be awesome if that were 1 second, but at this price you really can't complain.

  Overall, I recommend. A solid buy.

Works well, not perfect, there is some noise.  It is not perfectly clear. The USB charger output is spotty. This runs down my phone's battery without replenishment.  Very disappointed in this regard.  The removable head is very handy when leaving the vehicle. Easily removed and attached without pulling the adapter out of the power port. My adapter port is horizontal so supporting the Mpow requires a little work. Clean design, connects to bluetooth easily, and is not to bright at night. (I prefer a dimly lit interior.)

My only negatives here are the functionality of the USB charging port and the challenge presented using a horizontal adapter port to plug for the Mpow.  Overall I am happy with this in as much as it has eliminated the need for CD's and expanded the availability of music and other audio to enjoy.  Kinda saves me from the format changes to talk radio on two stations which aren't swine stalled into a narrow repetitive selection of bland commercial music.

I like the product for $25.  It works for occasional large screen TV HTPC.  but for heavy use, there's a Logitech version for $80
It disconnects after so many minutes of nonuse.  You have to turn off/turn on.
Perfect for cheap bluetooth keyboard with touchpad

I paid about $70 for this ODB II reader on a promotion that Amazon ran.  The product does the job it is supposed to with out a lot of bells and whistles.  I was able to quickly connect the unit and read the fault code from the car in about 30 seconds.

The documentation is a bit shakey -- it doesn't state much about using the product while the car is running.  Also, it doesn't let you clear out the car's fault without clearing out its own memory.  The only way to save code information is to make a printout from the PC application (and there is no 'save' option in the PC application to store the data on your hard drive).

Device itself works well enough.  I like that this version comes with a flexible pickup rather than plastic bar; the flexible ones work better.

That stated, the current price (as of this writing) of $19 + 5.61 s&h seems a bit high, especially when it is shipping from China.  At that price one can get the standard bar version, add a flexible piezo bar to the order, get free shipping and save about $6 in the process.

I don't often rate an item based on price.  But one must consider the market and this one doesn't seem competitive (ie, there are better buys out there).  The product itself is good.  But considering I'm the first reviewer it doesn't appear people are beating down the door at this price level.

On the plus side... this is a good pickup.  Has good sound and is far easier to mount and less invasive than a side-control-panel.

I bought this item because I needed something that would split off the audio stream from an HDMI cable. It was the cheapest one I was able to find. I assume most people would be buying it for the same reason. The device works as wanted. But, there are a few rough spots. The remote control connection to the unit seems to be spotty; ie one usually has to repeatedly hit the remote button for the desired port selection multiple times to get the unit to respond, as well as appearing to have a small range (probably around 12ft) to work. Changing ports also takes a few seconds to complete. But, all does function as intended. Considering alot of similar products are in the $100+ range, probably a good deal. I rated this product under the assumption 1 star being bad and 3 stars = average

Overall, the product does its job and the price is about right, so I can't complain. Most aspects have been already covered by other reviewers, I'll just make a few points that I feel were missed or not sufficiently elaborated.

1) Communications. The sensor pairs well with the base at a fair distance and with moderate obstacles (house floors and walls). However, the loss of pairing upon disconnection of power cannot be completely compensated by the ease of pairing. Especially when there are multiple sensors to pair. There needs to be either a power backup (battery) at the base or persistent memory for the device pairings.

2) PIR sensitivity. While I understand the chosen threshold for the detection sensitivity, I feel it is too high for some applications. I have seen some other devices with adjustable sensitivity (gain), but I feel that in this case it has something to do with the shape of the optical range. This is probably why the instructions ask for the sensor to be placed at a relatively low height but that is not always possible. In my case, I put it in the garage wall near the crew door and if I placed it any lower, it would be totally blocked by the car parked right in front of it. At a height of ~6ft, it does not detect any person until they are really close. It also does not sense the presence or movement of the garage door, which is only 12 feet from it, straight ahead. I find myself in need to experiment with position and angles to have the sensor detect anything useful.

3) Base/controller.
a) While I appreciate the independence from batteries, the loss of memory upon disconnection makes it close to being a permanent installation: you cannot pull it briefly to connect another appliance in that outlet, you cannot move it to another outlet - without having to re-pair it with its sensor(s).
b) The controls are inconvenient. To select the ring tone, you have to cycle through all options. If you miss the one you want, you have to go over the whole set again. Also, the switch between audible/visual/both is very flimsy, and has no good tactile feedback, so you'd know in which position it is, and the markings are so small, you need a loupe to be able to see it. Even the available values are badly chosen: the two settings with audio are at either end, so if you want the only silent option, you need to be able to find the exact middle, which with the ultra-short travel and feeble tactile feedback of the switch, can be quite adventurous.
4) Alarm. The options leave a lot to be desired.
a) The optical signal is ridiculous - a small LED light that can only be seen if you are looking directly at it. I'm not saying you have to have one but anything short of a flashtube is little more than a gimmick.
b) The sound is acceptable in some cases but I find its volume range to be short of my expectations. My house's doorbell is louder. Your alarm needs one more, louder setting to be a viable solution in anything but a small apartment. And while I appreciate the variety of sounds it can make, most of them are too soft to be useful, and combined with the difficulty of selection outlined above, it makes them unusable.

I ordered this for an ultrazoom camera. It does work and allows much finer control than the fluid pan head on my tripod. However, it is not perfect so I will share the shortcomings imho.
1. The control knobs are very stiff. I was expecting a smoother movement on the adjustments but it was actually quite stiff. I tried lubing the threads on the adjustment but didn't seem to help much. I think it is just rough cutting on the threads. Hopefully it will smooth out with use.
2. The amount of adjustment is not very big. The up/down adjustment was better than the left/right. In a 1 hour session of stargazing... I had to adjust the adapter several times which was a distraction but not a huge deal.
3. The adapter was not quite as sturdy as I had hoped. I have a good tripod and this was definitely not as sturdy as the tripod was. Even with the relatively light camera attached, I could discern a bit of flex so I would imagine a heavier scope would be a problem. Ok now having talked about the shortcomings... I will say it is the cheapest deal going for fine adjustment on a tripod adapter so given the cheap price, I am happy with it. I won't insult anyone's intelligence by saying it compares to a quality geared head but if you want to get a low cost option that is miles ahead of struggling with a cheap tripod... this is a good value for the money and I am glad I bought it.

I like the earpiece, but I have three minor critiques that prevent it from getting a 5-star rating.
1) it's only one earbud (as shown in the picture). i kind of like having the option to use two, to better drown out background noise.
2) i'm doubtful of its durability, especially if treated roughly. no problems so far, but the wire feels quite thin.
3) the sound quality and clarity are not the greatest. sometimes my conversations sound muffled or like they are happening "underwater."

but for the price, i think these minor drawbacks are very acceptable!

Good, not great. Good price for what you get. There were definitely some quality control issues with my first unit - radio interference was one issue, the other was a very chappy 3.5mm jack. It bended originally and it eventually snapped off completely inside my computer. I was able to get it out and fortunately Amazon replaced my unit.
