I have been rebounding for over 20 years I have purchased two other brands of rebounders, only to have the springs break. I had heard of bellicon before but I did not want to invest the money in a bellicon . I thought the bellicon was to costly, But bellicon recently had a sale going so I decided to make the investment. I am so delighted with the Bellicon, it's unbelievable it feels good , it's quiet and best of all the quality is well worth the investment. My only regret is I wish I could purchase another one, I would like one at work also. I Love It! bellicon is by far the best.
