Has anyone ever used anything like this before?

Its not too much money and I could probably make the money back by doing other peoples cars. Wondering if anyone has ever used a tool like this and how hard of a job is it to actually roll your fenders.

 

i've always just rolled them with a baseball bat, or a large pipe.... if you go slow you can do it really wel.

 

I have one and it works great. I get alot of guys asking me to do three of theirs after they do one with a baseball bat and crack their paint.
