Hey, for $20 dollars and the lack of really good games for the Wii, this one is worth it!

Overall, the game is itself is a hell of a lot of fun. The zapper itself doesn't really help much. I find shouldering it and looking down the controller was the best way for me to use it. But i was really impressed how fun the game was, played for hours until my wrist hurt! Some of the levels are extremely challenging. And you'll have fun going back trying to bump up your score on each individual level.
So get your butt to walmart and spend $20 so your wii will actually get some use, instead of just being turned on occasionally for visitors to play tennis!
