Most of the move release titles do not support this controller.
I had hoped it would be like the wii nunchuk, but for games like Sports Champions you need 2 move controllers as the navigation controller is not supported.
My advice it to wait until there are more games supporting this controller.
Furthermore there is no safety strap. If my kids end up putting this controller through the TV I will send Sony the bill for being too tight to include such a basic component.
