I originally was excited when I saw this keyboard because it has a trough in the front where I can put my tablet or phone, which would allow me to keep an inexpensive, backlit keyboard near the bed to use with my phone or tablet whenever I got in the mood to write and didn't feel like using my thumbs. The trough isn't wide or deep enough to hold my phone in any usable position while it's in its case, and I don't like the idea of taking it out of the case all the time. Luckily I found a magnetic things that sticks to back and lets me use the trough that way. If you have a thinner case than mine, it could work better. It holds it perfectly without the case.
The rest of the keyboard is pretty cool, I've discovered. You can turn the backlight on and off, adjust the brightness, and change the color to several different solid on colors, a static rainbow, and a few moving patterns. The moving ones look cool, but especially if I'm typing in the dark, I don't know that a moving light is the most practical. But it certainly looks cool. I should note that the backlight doesn't quite make it up to the music and volume keys. Also, while the letter on the key lights up well enough, most of the light spills around the buttons, so you see both the letter on the keys and the outline of each key a little brighter than the letter.
There are also dedicated buttons for the calculator, the "my computer" file manager, one for a blank browser page, and one for email. When you first hit the email button your PC asks what app to open. I usually just use gmail through the web interface, so I don't there's a way, between the keyboard and the computer, to make that button work to my specific email page. The volume buttons all work as expected, and I don't have music on this PC, but the music control buttons appear to be sending the correct signals if I had any.
I haven't had it long enough to comment on the battery life, either with or without the backlight being on. LEDs draw very little power, so hopefully it lasts a while.
I wish it were bluetooth rather than needing a USB dongle, but it's still easy to use, you just need to remember to take the dongle out if you want to use it with a different device. There's a little nook on the bottom of the keyboard for tightly storing it, which is helpful.
The buttons are pretty quiet. They have a good amount of give when you press down on them and spring back quickly as you'd expect and would only notice if it doing it wrong.
Bottom Line: While this isn't a powerhouse bonkers gamer or developer keyboard, for just typing, it's perfectly great. The backlight is nice for when it's dark and it's relatively quiet if that is important to you or whomever you may be typing next to. If you're interested, I'd recommend giving it a try.
