Great for very low Price

Great headphone as far as sound and quality of audio. The price makes it even better. The only thing I do not like about it is that after an hour wearing them your ear actually hurts. But just be smart and take them off your ear every half of an hour. Great product for the price.

Here is why this thing is five stars:

Super cheap price and is quite small (perfect for my Civic).
For a vented box, this plays the set frequencies pretty good (installed a Fosgate P3 10").
Might be able to get more deep bass and sound pressure with a larger box but this thing is well
rounded and actually plays lower notes fairly tight; I imagine this is from the small
cubic feet volume. Be sure to glue the connector to the box as it is quite cheap.

Happy enough with this as my whole sub setup was about $165

I thought it was a very good product for very little money.

If your phone has a 2.5mm jack, this headset is incredible for the price.
Sound quality in the earpiece is very good - easily as good as when using the handset of our Panasonic cordless phones, and voice quality for the other caller is good as well.
There is a switch to toggle muting the microphone which makes it perfect for conference calls.
The headband is secure, but also comfortable for both my wife and me - the headset is very light, so the band can keep it in place with next to no pressure.
You get a lot of functionality for a very low price.

Since this is such an inexpensive "faux Keurig," I was skeptical about the quality, but I wanted a very small one since I would be using it in my classroom. It makes a very good cup of coffee in a very little time. I used it almost daily for a year, even using it this summer as our big coffee maker broke. You can't go wrong for about $20.

Surprisingly good quality at a very low price.  All my photos fit fine.  The margin for notes is helpful

Very good for a very cheap price. If you don't want to spend much but have lunch containers, these are every bit as good as the more expensive kind. I have both.

The 5 star rating for this product is only due to its very low price. The filter itself is of acceptable quality, but is not spectacular by any means. It does what I need, which is to protect my $1600 lens while the cap is removed, so I have no real complaints. I have a nicer quality filter on the lens right now, but keep this one in my bag as a back up. Excellent deal at less than $3, so I am very happy with my purchase.

Very good sound quality.  I was very surprised considering the low price.  I have yet to take them to the gym but just playing around with them they work great!

Great for the low price. Simple to use. A bit awkward at first  that the light  sort of juts out like a flashlight, but  you get used to it. Seemed like you would have to pay  $75-100 to get a light  this bright from the name  running light compaies.

UNBELIEVEABLE, BUT TRUE; GREAT PERFORMANCE FROM A VERY LOW COST PRODUCT.  I HAVEN'T HAD ANY PROBLEMS WITH THIS PRODUCT AND FOR THE PRICE, I AM TOTALLY SATISFIED.  I HIGHLY RECOMMEND THIS PRODUCT TO OTHERS.

Wonderful for the price, very durable, purchased 15, and none were DOA but all are exceedingly slow, maxing out at about 2.5mb/s even on a USB3 port.  Dinging only one star because of the low-low sale price.

I use this for a mac desktop I have hooked up to a TV. It works at a distance of 15 meters (without anything in the way) and the keyboard provides good feedback.

It does exactly what I wanted for a very low price, and the battery life has been excellent. If it fits the bill for you, you won't find what you need for a lower price. Consider buying the silicone keyboard cover designed for this item to keep the keys clean.&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/COSMOS-Ultra-Thin-silicone-soft-keyboard-cover-skin-for-Logitech-Wireless-Touch-Keyboard-K400-and-K400r-Black/dp/B00DE7SHII/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">COSMOS Ultra Thin silicone soft keyboard cover skin for Logitech Wireless Touch Keyboard K400 and K400r (Black)</a>

This tablet is very nice and a very good value for this low price! It runs smoothly and it looks like one of the higher priced ones. I would strongly recommend this to anyone looking for a great product but with a tight budget.
