Pros: This keyboard works great for what I use it for. I have a computer in the living room hooked to a TV and we watch netflix and other movies on it. The volume hotkeys work well with Windows 7 and the range is good enough for me to control the computer from over 20' away surprisingly enough. The rechargeable function of the keyboard is also quite nice.

Cons: Keys are really small and hard to type on, this is not something that one would want to use for more than basic navigation of a computer. There is a timeout function on the track ball, my guess is to conserve battery. It can be frustrating, at times you will think that the keyboard is off when really the trackball is just asleep. The charging light is mostly irrelevant. If the battery is low or reception is bad, mistyping will happen frequently.

Overall Review: Know what you're getting into with this. It isn't a keyboard you want to type a paper on, but it works well as essentially a very large remote control with a lot of functionality.
