I received this as a Christmas present after (foolishly) putting it on my list. Let's just say I regret costing my brother $65. Right out of the box, it didn't work. I adjusted the batteries, played around a bit with the USB receiver, and it finally connected. After about 10 minutes of use, it disconnected. Repeated steps 1-2, used for an hour this time, and it stopped working again.So I called tech support and got the answering machine. 10 times in a row, on 10 different days. Emailed them. Never got a response.My advice is to spend your money more wisely and get a better product. This one is not it.
