Summary: Don't listen to the people who are complaining about this keyboard. It's really nice. I haven't had one problem, and I would rather occasionally plug it in to charge than have to futz around with replacing dead batteries. You will not have to plug it in to charge very often. I use mine fairly frequently and it lasts for over a month without having to plug it in.
Summary: I'm a software developer, so needless to say I use my keyboard a lot. I never dreamed that I would spend this much on a keyboard, however, when I'm using another keyboard I'm wishing I was using this one. Its really the simple things that I love about it. 1) Its quiet, but sturdy. It feels like a mechanical keyboard, but sounds quiet like a laptop. This is something I never thought about until I experienced it, and now I'll never not notice it again. 2.
Summary: Would love it if the buttons were white/clear and the key labels were black. Wargames style backlighting is what I am referring to. Good feel and action. Worked fine for a couple years, had unfortunate accident with it broke a couple buttons off.
Summary: Really like the keyboard to an extent. It's great for when the lights need to be out or a dimly lighted room. However, I don't care much for the recessed keys. It's very difficult when gaming and the raised keys I had on my previous keyboard was so much better.
Summary: Naturally these warranties are tied to a particular serial number. The contract says it won't repair a device where the serial number has been altered or marked out. Herein lies the rub. The refurbished keyboard has the original serial number marked through with a felt pen. The only serial number to be found is on the box.
Pros: If you are lucky, you will receive a clean, fully operational keyboard. I was lucky.
Cons: My issue isn't with the keyboard but the extended warranty purchased for it.
Summary: Overall design is great and the illumination is beautiful. I was tired of the small keyboards they make for Macs and wanted a real keyboard with the numeric keys. I searched around and could't find anything and saw the Logitech K800. It was exactly what I wanted, however, the packaging does not tell you if the keyboard is Mac compatible. I read online that it should work with a Mac, so I purchased it hoping it would work.
Summary: 2. When paired with logitech mx mouse the keyboard loose connection you need to put the receiver some what really in front with no obstruction so it wont get disconnected time to time but if your not connecting other peripheral on the receiver it should work fine
Pros: 1. Backlight is good love the proximity sensor.
Cons: 1. The keys are somewhat compact unlike the other keyboards
Summary: This is an awesome keyboard but its big. You can see that the Logitech icon is in a big space and that space is what makes it too big. Maybe for you this is an advantage but for some people like me that their desk are not really big it is bad.
