Ive not found them to be slippy. Can even due landmine press on it and floor press for chest. I figured I would pay extra for comfort and longevity but I was duped on longevity lol. So in short. Overall not elite, but good and no complaints. It came in pieces but all the parts and Allan wrench were in there & didn’t take too long. Fit-flops all the way for me now! I’ve been using this product for several months now, and while I really like how it works and that it has a really mild scent, I really don’t like the consistency. These are really not practical for anyone really and I think are actually quite dangerous. 3- No tienen instructivo para el Elite-pro2, ni en la página ni en ningun lugar.
