Paddle Bust

What is the technique in using this contraption? Does anyone know? We had one of these things a few weeks ago, I don't remember where it came from, but I new were I was going with it. So I did what anybody else would do I thought about it and came to a decision. And guess what? I picked it up and decided that today was going to be the day,but after several smacks to the face and my body and just struggling the string and ball popped off. Whyyyy!!!!!!! Once again I've been defeated! Now, I don't know about you but every time I've ever tried paddle ball I've failed miserably. This "game " has to take some major skills or something. One day I will get some kind of consistency from this, till then a few more smacks to the face I'll have to endure. Any tips from you pros out there? Fun, fun, fun! Peace out.
