I'm a 62 year old lady with lots of health issues like scoliosis, osteoporosis, celiac disease and more! I've had a lot of upper body limitations recently so I've been spending a lot of time bouncing on my Bellicon. It gives me such joy! It has also improved my balance and helped with bone density issues-big concerns with my health history. I've been happily bouncing in my back yard and lost a rubber tip since it had rained so much. I emailed the contact address and presto-I now have not one but 6 new rubber tips! I carefully researched many rebounders before settling on the Bellicon. I was hesitant because of the price but am so grateful that I went for the gold. I look forward to decades of happy bouncing-esp with all my new tips. Thanks Bellicon!
