I have had this keyboard and mouse set for a few years now and don't have a single bad thing to say about it. This is the first wireless combination I've ever had and I'll never go back to all the wires. I've moved a few times and it's always been easy to take down and set back up. Both the keyboard and mouse easily find the signal, even when there's objects in the way. My keyboard sits lower than the receiver and still is able to pick up the signal with no problems. The battery life on both are good and I don't feel like I'm replacing batteris frequently at all. When the batteries are getting low both the keyboard and the mouse start to flash red and gives me plenty of time (a few days even) to get new batteries in there.
