Great Keyboard for night owls, working on 3am projects or everyday typing!
"It’s a fairly simple keyboard. You won’t find an extensive set of macro buttons, dedicated media controls or other special features. There are some Fn+key functions but even then they are fairly simple. The main feature of this keyboard is the illumination functions. The backlighting is automatic by default but can be changed in the software. The keyboard also allows you to manually change the brightness as well as disable the backlight.
The keyboard uses Logitech’s newer Unifying reciever which allows up to 6 devices to be connected. The K800 is wireless (it also comes in a wired configuration) and uses a rechargable battery. It’s charged by a standard micro USB cable. The battery life is excellent. With a lot of use, mostly with the backlight on, it still shows full battery after about 3 weeks. If you need a backlit keyboard and can get it for a good price, this is a definite buy."
