Worked first time, no setup required. The buttons feel a lot cheaper than the original Roku remote, and the IR output is obviously a lot weaker as it doesn't always register on the TV. You must be close enough to aim directly at him. That can sometimes be a bit disappointing. It definitely works as a cheap and convenient Roku remote replacement, but the quality is pretty poor.
