"great keyboard !"4.5 starson by bl14
Pros: Excellent back lighting, quiet, pleasant typing, multitude of feature keys, cool design
Cons: No real cons, just a little bit**ing I will do in the summary.
Summary: This was literally a gift from heaven. My Logitech Alto ( a horrible peace of sorry junk) died during the warranty and Logitech arranged for replacement. Because Alto was disconnected, they decided to send me the K800. I could not believe it. K800 is as good as Alto was bad.The back lighting cannot get any better. The Keys are great. Typing is a pleasure. Bunch of feature keys, i did not even get to exploring all of them. Just love the calculator key. Cool design, takes little space, does not move like crazy.
A minor annoyance: Unifying does not work with my Logitech mouse( it probably has to be one of their latest models) and unlike Alto, K800 must have that USB device. This way I have now two USB ports blocked as opposed to just one before.
Anyway, I great key board. Absolutely recommended.
