Summary: The keyboard arrived with box undamaged. We opened the box and boo, four keys were flopping around in the bag (CTRL, Caps Lock, "0" and "."). My wife tried to snap them back in for 30 minutes but no such luck. What can I say, I really like logitech but this is a major fail. I found many other reviews from users that had the same problem, so this is not a defect on my keyboard, it's a defect with the K800. Don't buy it.
Summary: I'm not a gamer nor did I use the keyboard on a full time basis and yet the ''P' and the "W" broke off in less than a year. I was surprised as this keyboard received such high marks. I will not purchase another Logitech keyboard - the sleek/simple format was nice but the quality is poor.
Summary: This keyboard was great for a few days. After the breaking in was done, this keyboard fell apart. At first, a couple of less-frequently-used keys jammed several times a day. Within a week, every key was physically jamming every time I pressed it. I had to exert considerable force to type anything. Worse, it had electronic problems (e.g., misinterpreting keystrokes, missing other keystrokes, etc).
Summary: I use alot of Logitech products and this one is just not one of there better ones. after spendng several hours trying to get this workng it lghts up and that is about it. changng system file names is not something everyone can do and it didn't work anyhow .
Excerpt: I purchased this keyboard after trying only the wired version in the store. The Wirless keyboard version was on sale for a cheaper price and so I purchased it thinking that wireless is even better. Unfortunately, when I got home and tried this keyboard, I found that the keyboard was not as slim as the wired version. The keys had much longer travel and were the smaller chicklet-style keys. I found these fisher-price-like keys clackity sounding and of low-quality.
Pros: F-Keys Light up
Cons: Battery Two Day Life, Fisher-Price Style Keys, Plastic- non-tactile feel, USB Recharge Poor
