Horrible quality. Super flimsy and no resistance worth trying to work out with unless possibly for an elderly person, but they fold/roll immediately. I unpackaged and bypassed to x heavy black band as all others were not worth trying. As soon as I put on and did one m9ve it folded as shown in picture. Bummer... would rate 0 if I could. I don't even work out much, was hoping to at home with these.
