The Cellerciser is the best rebounder, no competition. Even the more expensive bellicon has an ineffective 0 resistence bounce, and rubberbands that stretch out and break. David Wolfe invited bellicon 1 year to his Longevity now conference, and due to the lack of quality and customer complaints, hasn't invited them back. Guess who is currently invited to his Longevity now? That's right, David Hall's CELLERCISE!!!
