http://www.mansionselect.com/autopartner.html Anyone use or even seen any of these? It looks like an amazing idea to me. It feeds you balls, you feed it back and the cycle continues until you mishit too many times. However, one thing it doesnt tell you in the product description is how fast it can shoot balls at you. Though this doesnt have the variety of hitting against a wall, it looks amazing. Any feedback on this would be greatly appreciated!
