Good action but the keys are not lit.

Keyboard has a nice action and I like it even though it does not solve my original problem.  I should have noticed that the actual keys are not illuminated so the keyboard is no easier to use for regular typing in poorly-lit environments.  The colors are quite cool however.  Have not used mouse but it is a large one which may be good depending on the user.

I really like this keyboard.  I used one just like this years ago at work.  The keys are full travel.  I wish it had multimedia buttons with volume control.  I ended up adding a volume icon to my desktop and set the F-9  button for the volume control by setting up a shortcut with %windir%\System32\SndVol.exe -f 49825268 as the target.  Now after pushing F-9 (or any key you set the shortcut to) I can then push "end" for mute and use the arrows to control volume.

I like it a lot, I just wish the lights were on by default.  It would make booting my multiboot system easier in the dark.  The key switches are solid and I feel more accurate typing on it.  I learned back in the day on a mechanical keyboard.

The keyboard looks cool. The keys have a good feel to them. I haven't had time to game with it yet.
The lighting on the keys is excellent and is well done.
One thing I'm getting used to is that there is the macro keys on the left and I'm used to the caps lock, shift, etc. keys being in that position so I'm constantly accidentally hitting one of the macros and it throws me out of my current app and into another one.
Not the fault of the designers, just something to consider.
The reason for four stars and not five is that the tilt sucks. The keyboard doesn't tilt up enough so it feels like your fingers are REEAACCCHHHING over the keyboard.
Setup was simple. Drivers auto loaded in Win 7 64bit
I don't use NEAR the number of keys I could be using.

It is a wireless keyboard with missing functionality and a generic wireless mouse. Very easy to setup on a windows 7 computer. Key presses are a little soft, but it offers a pretty good typing experience. The key layout is pretty good.

Logitech missed the boat with notification lights on the keyboard. There is no light to indicate that the keyboard is turned on. This feature would have been useful to let you know at a glance that the keyboard is still turned on. Further, there is no lights to indicate which key locks (Scroll and Num Lock) are on. The Caps Lock key does include this feature and the other keys should have been done the same way.

Reasonable keyboard but some of the spacing and key sizes are different and not as easily used when typing fast.  Illumination is nice and easy to use in lower light settings.  Key action is not as smooth and noiseless as some other keyboards like the Mac keyboards.

Pros:Nice and clicky keyboard, great item to have for gaming sessions in the dark
Cons:Lots of power required
Mine came with the numpad and a few other keys not lighting up at all

This keyboard is great other than the A key not working sometimes. You have to press it a few times for it to register which can be pretty frustrating. The colors swap easily and are great.

I love this remote.  its backlit, and most of the buttons work on a pie.  But I Hate the keyboard and the weird alt button to press half the keys, which are not backlit which makes the keyboard completely useless in the dark if your actually using this as a computer keyboard, but i guess thats not really what it was made for, so 4 stars.

The game is great just know that the font in the game is small and may be hard for some poeple to read. Other than that its a good game with some good action.

While it feels, and sounds, nice using this keyboard, I find the keys a little too close together for completely comfortable gaming. The grey WASD keys make the keys feel even closer as they're sloped a bit.

The effects are kinda cool, being able to light up only the keys you need is great for gaming in the dark.

I wish is was a backlit keybaord, but that was my mistake. otherwise the keyboard is an exact fit and works well.

I like the feel of the keys, which are also backlit. It's slim and the I'm a gamer who prefers to use the arrow keys instead of WASD for movement, so I like how the number pad, and other keys are nearby to the arrows (one of my biggest complaints about main-steam gaming keyboards).

Pros:
Beautiful colors: I love the multiple colors and how it can breathe from one color to another.

Cons:
Slightly unusual enter key. I got used to it on the first day but at first my fingers were trying to press the wrong spot while typing.
Doesn't work well for many games.  Specifically, the problem happens when you are asked to hold a key to achieve some result.  I have experienced this problem on Shadows of Mordor, Titan Fall, and even the Witcher III.  For example, on the Witcher III it says "hold e" at places of power; unfortunately with this keyboard the hey won't hold long enough and the action is never completed.  I know that the keyboard is the problem because I plugged in my old keyboard and the problem was instantly fixed.  If it wasn't for this very serious issue I probably would have given this keyboard 4 or 5 stars.

Bottom line: Works fine for typing. If you're a gamer look elsewhere.

Really nice tactile feel to the keys. Pairs easily. Has rubber stops at bottom to prevent keyboard sliding. Very sturdy build.
What I hope they had - at least a light to indicate the keyboard is on or a caps lock light. Because when it is on standby, you have to depress any key and wait about 1 - 2 seconds before it starts up. So you'd be like typing and nothing comes out.

Otherwise, I think it's a great bluetooth keyboard for the price.

It was a good action movie if you don't mind not being able to see any of the action or really the movie.
Every now and then it has some good scenes, but most of the movie is pitch black even after playing with brightness and contrast settings.

Keys feel great but it's very difficult to see the letters on the keys. There's no backlight and the letters are printed in dark grey on black.
