good
Good jumping rope. I am able to do double unders with these. The cord is a bit too short, leightweight and thick. The tickness comes from the rubber layer over the cable. the cable itself seems to be made from aluminium (not 100% sure). Jumping is easy because of the bearings. good product.
wonderful
ottimo.....perfetto
