eastwoods fender lip roller(have you used one)

Has any one ever used eastwoods fender lip roller? It looks pretty nice but expencive! might have a couple people who want to have theres done and can split the cost. I would just like to know how good it works or if cutting slits in the lip and bending them back is a better option http://www.eastwoodco.com/jump.jsp?itemID=6159&itemType=PRODUCT

does any one have one of theses they want to get rid of?

I am also wondering if you can stretch the fender flare out more after the lip has been rolled all the way? Or does it not have enough leverage?

thanks!!
