Comments about Product:
My 12 year old got the one that he was barely into, weight-wise, and initially found it quite difficult to get going. He eventually got on to it, and really enjoyed going out and using it -- challenging himself to do more and more jumps in a row until he was into the 100's.
Unfortunately, the rubber tip split and broke off very early on, and bouncing on the metal end was both noisy and damaging. I'm in the process of looking for a replacement tip, because he misses this thing so much.
