Good for the price with a lot of functions.

I gave it 4 stars because it is cheap with a screen. Putting a price aside, I would give 2 stars.
It is an audio system so my best interest for it was sound quality which is not good.

Pros.
1. Screen and its quality (not the best but much better than cheap aftermarket rear view screen)
2. External ports (usb, SD, aux out, rear view camera, video/audio input, sub woofer out put)
3. Video play (I haven't tried though)
4. Price.

Cons.
1. Sound quality is not good (it feels like cheap ear buds sound with over exaggerated bass, lack of high)
2. Rear view function only work when it is connected to backup lights. If hooked up to positive, it only works as rear view camera. No other function.
3. buttons are flimsy and a stubborn to push.
4. Can't listen to music while adjusting settings or using rear view camera.
5. A little hard to navigate through settings and albums.
6. Video play only works when car is parked unless connected to ground (then parking brake light will stay on)

Yes, it is cheap so I didn't expect much so I regret it.
Video quality is above my expectation for rear view camera. Much better than my cheap LCD screen.
I add an on/off switch for rear view function. It is too much work for me to re-do all the wiring from back of my mini van trunk (I already set a camera and a LCD screen) so I just need to hit the switch for simple rear view function.

Overall, it is okay unit, good for the price. but I wouldn't recommend it if you want some quality sound and rear view function.
However, if you can be happy with ok sound and didn't do the wire work yet then this would be great for you.

Not bad.  Most of the functions are about the same.  Needs a function that will fun through All options.

This is a very inexpensive yet versatile little multi-function machine.  I'm satisfied with all of the basic functions (scanning, printing, copying) and love the wireless feature.  I'm using Windows 8.1 and the drivers are current for Acrobat.  Setup is a bit of a chore and took me about 90 minutes but when it was over the machine worked flawlessly.  Recommended.

Programming is fairly straightforward, with room for some sophisticated operations with the timing delays.  Documentation is decent.  Great backlighting.  The varied shape of the buttons and the layout helps using the remote via tactile feel.

Not perfect, but a very good budget alternative to something like an expensive Logitech Harmony.

Programming is a little finicky but it works far better than I expected for the price and there are a ton of resources online to help with setting up.

A good bundle of features for less. Very stylish and functional. The only difficulty I have with it is setting the time. After I set the time it seems to have its own time reference and falls behind by a few hours. Other than that I would say the phone is a good buy.

Has multiple functions that are relatively easy to use. It doesn't feel as solid as I'd like but hopefully it is good enough quality to stand up to kids' use.

Great deal.  It's not flashy, it's functional and works well.

Fairly cheap build quality and it needs 2 buttons for all the multiple functions.

This radio has a lot of good and useful features.  Everything worked when I got the product.  It feels a little on the cheap side so I am concerned of it's durability over the long haul.  The speakers are on the weak side and seam to be a little tempermental.  Everything but the tuner has a nice bright digital readout, it would be nice if that was digital also.  It's got a nice look and is way better than the last radio I bought for my bedroom.  This one should fit it's purpose well.

This is an interesting mouse. It is kind of big, though fits well in the hand. It is a bit plastic-y and seems a bit hollow. My MX anywhere mouse seems more solid and better built, including the scroll wheel. That said - the mouse works very well and it has a plethora of functions. Charging the battery is a bit of a pain through the USB cord - but at least you can still use the mouse while it is charging - though it feels a bit awkward with a long cord sticking out of the front of your mouse. For the price - I expected a bit better - I have used Logitech mice for the past 10 years and feel the quality is getting less and less with each iteration.

This is a versatile controller for a reasonable price.  The ability to add more zones as needed is very helpful.  The USB integration is a great function as well if you like to configure on a PC.  I have found that it is easier just to program it from the controller itself.

Functions perfectly at a reasonable price.

For the price, you get a lot of functionality in this package.  The knife is very sharp out of the box (much appreciated, so I don't have to sharpen myself).  The paracord and firestarter are niceties, but you never know...  This fits well in a small pouch or backpack.

This is a really good mouse for the price.  Looks good, feels good and has plenty of useful features.  The software works good to map your buttons.  The different DPI settings are easy to change and work great.  You can set different colors if you like.  The removable weights is a nice customizing feature.  No complaints at all.  Would definitely recommend for those looking for a cheap gaming mouse with many useful functions

For the price, very functional.  This is the second one I have purchased.  Its not made of thick fabric, but it holds a lot of books and works well.

Kind of bought this on an impulse, but I've enjoyed the use of it so far. The controls aren't entirely intuitive, which is why I docked a star, but it seems pretty accurate and does all the functions in the description. I just moved into a new place and was trying to map out rooms for furniture and area rugs I was buying, it served that purpose well for the price.
