Summary: Bought this after my girlfriend spilled wine on my previous keyboard (don't ask...). The quick access buttons are convenient, especially the volume and mute since my speakers are hidden behind my monitor. Battery lasts for several months, so no complains there. I have the wireless USB plugged behind my computer tucked under the desk without any communications problems.
Summary: This is a very nice keyboard. An extra nice touch is that it came with the required AAA batteries and they weren't some cheap brand, they were Duracell batteries. It was easy to install, simply plug in the USB transmitter and the batteries, then with Windows 7 it self configures. Make sure that you put the batteries in the keyboard before you plug the USB transmitter into the computer.
Summary: We loved this when we first got it. Easy to use, runs on two AAA batteries, but suddenly the hyphen (-) key has become locked and will not unlock. Totally useless now. Well what can one expect these days I guess!
