I'd give it zero stars but that is not an option on this form.
This virtual ping pong game does not work. The game unit either does not detect the paddles or crashes every time we try to play it. We have put in fresh batteries and tried everything. It could be that we have a malfunctioning unit, but it's not worth it to try to return it, buy another one and have our child disappointed all over again.

A piece of junk.
