I second this although I'm a little leary on the 30ft specs logitech says. I sit about 10ft from my htpc which sits in the corner to the right of my tv and couch. I have the usb receiver on the front of the computer and I have to point the keyboard at the computer for it to work consistantly. Just remember that it works on the 2.4 GHz wireless connectivity with Logitech Unifying technology so if you are using anything else that works on the 2.4 GHZ frequency, it's possible...
