Question: At first I had my USB receiver plugged into the back of my desktop (10 feet away, but blocked by sub-woofer and coffee table) and was having issues with a lag with the keyboard, I did not have a problem with mouse reception without direct line of site.<br /><br />I found a little 2 foot USB extension to point the receiver in my general direction while minimizing obstructions and haven't had any other problems with lag.<br /><br />Just keep in mind that you will need a 80-90% clear line of site between keyboard and receiver.
