Pros: You could maybe get buff hands from using this pump.
Cons: Got nothing from this!
I would pump and pump and get nothing!! Seriously the worst pump ever. I actually brought it back to where I bought it and got a refund. Maybe it was a defect, but I think I spent what seemed to be a week doing nothing but trying to pump. I Would not buy or recommend this pump . Save yourself the time and fustration.
