Iron gym

Has anyone used the iron gym? http://www.theirongym.com/

I want to get something similar to that, something I can use my door frame to do pull ups without having to screw on anything.

Does it damage your door or anything?

This thing is awesome. I have it on my bathroom door. I do it each time I walk by it. The only that sucks is the door can't obviously close with it on. But if I take it off, I can't impulsively do it each time I walk by the door.

Does it help that much? Do you see and feel a big difference?
