Summary: This is a very nice keyboard. I bought this one because my previous backlit keyboard keys were coming off due to cleaning. The angle lifts on the K800 collapse when I move the keyboard towards the monitor. I move the keyboard around a lot and this constant collapsing is unacceptable.
Pros: Unified RF receiver, rechargable, construction quality is quite good.
Cons: The batteries were DOA. The keyboard shipped with (2) Sanyo Eneloop 1950Mah NiMh batteries that were completely dead and unrecoverable, resulting in the bottom battery LED flashing red on a 1s constant pattern. These are pretty easy to replace, if you have some spare NiMh AAs, which is the route that I took.
Summary: This is a nice keyboard that is average in just about every way. Cordless and illumination are very nice, feel and battery life and touch-sensitive illumination are very average. I would not recommend this keyboard for heavy use computers as you'll be recharging the batter every day. I also think the price is a bit high.
Summary: I'm not sure what the actual problem is, but it's extremely easy to press multiple keys while typing. I don't know if the keys are larger than standard, or if the shape of the individual keys lends itself more prone to accidental "fat fingering", or if there is a spacing issue. I have to continually backspace as I typo every few words. Obviously I don't have "perfect flawless" typing skills, but I've never had typos like this before.
Summary: i bought this keyboard around the same time as my purchase of your G700 wireless gaming mouse, and your wireless numeric pad, between 6 and 9 months ago. A couple days ago, the "E" key started popping off. I looked in your forums, and found a post of others with the same problem. i followed the advice of one of the posters and noticed he was suggesting the fix sorta backwards, attaching the plastic hinge to the keyboard, and then attaching the key to the hinge.
Summary: I'm really happy with the lighting, features, and touch of the keyboard. Unfortunately, it took 2 weeks to break a clip, and without the SetPoint software, that hand sensor thing (with 5 SECOND light deactivation) would drive me absolutely nuts.
Pros: Good lighting. After reconfiguring the sensor using the software, quite happy
Cons: Poor workmanship on the clips, and USB cable broke within a month.
Summary: this keyboard is pretty much like it sister (corded Illuminated Keyboard). i still do prefer the corded one but i bought this one for a new experience, but i was kinda disappointed specially comparing to its sister. the keys are not as comfortable and smooth as it sister. also i think the biggest problem Logitech made that made me very angry about this product is that there is NO num lock indicator on the keyboard and that is just unacceptable.
Summary: It's sad, this keyboard has almost everything, but this is almost ruined by a few bad decisions. The thin and silent keys are a pleasure to use, really. The illuminated feature, though not at all the primary reason why I acquired this keyboard, is a nice touch - it's also good to be able to control it from the keyboard itself. And finally, the overall look is quite a success.
Summary: The keyboard itself is what I wanted. But when I use the upper case letters, sometimes the first and second letter will follow and be in upper case. THAT forces me to backtrack. Such as (that) above. Other than that I have used LOgitech products for about 10 years with no imperfections.
Summary: This was a Great Keyboard Finley one that light up so I can see at Night.Ya know its these little things that realy mean alot ok the keyboard was great untill the keys started sticken, Now I live a lone no fluids or food near my computer, then it became so bad I could no longer use it. Oh ya Just after 90 days no luck getting a replacement cant aford another 100 bucks.
