Prima sports equipment for young and old. I am very satisfied of the processing, the material of the plug-in system. It served its purpose for my daughter to play and for me to do sports to wonderful. I find it very convenient that the tire brings a certain weight, which is already given by the material here. This makes the hula Hoopen easier and "nipple-shaped waves" gently massage the "love handles" off (one can at least imagine ;-)). Strong buy recommendation from me.
