Summary: The 3 star rating i'm giving this keyboard is an average of the 4 stars I'd give it for ergonomics combined with the 1 star I'd give it for trouble-free installation. Unlike so many of the logitech keyboards, there is no software and no documentation that comes with the keyboard.
Summary: I bought this new GK-K6800 keyboard about a month now and after regular usage it started to give me some problems.It seems as if the usb wire has a damage in it so it keeps chipping in and out
Summary: Love the color/design/positioning of keys too much to purchase a different keyboard.
Pros: Volume knob, multimedia keys, color, design
Cons: Have a tendency to die very easily. One died out of nowhere after three weeks (only the volume knob worked), so I purchased a second one. Got a SINGLE DROP OF WATER on a key (condensation from a cup on my fingers) and it must have seeped down onto the board--instantly fried. Bought a third and this one's going strong.
