This is my second rebounder - my first was a JumpSport and my new one is a bellicon 49" with folding legs. Here is my comparison of both: 1. Both are quiet. They use similar technology utilizing a bungee cord type of suspension system - no noisy springs. One bonus that the JumpSport did have, though, is adjustable tension. With the bellicon, you have to select the "firmness" of the tension bands and they are not adjustable (but you can purchase different bands if you choose.) 2. Folding legs on the bellicon are a HUGE convenience. It makes it quick and easy to store or transport. Even though my JumpSport was much smaller, it took up more storage space. 3. The bellicon has a softer bounce. 4. bellicon is bigger. I LOVE bigger! You can do moves that you can't do with a smaller mat. More variety makes for more fun, less boredom, and a more dynamic workout. You can focus on working out, not where you have to place your feet so you stay on the mat. I can't emphasize enough how much more enjoyable it is with the larger jumping surface. Summary: For me, the 2 big sell points are the bigger mat and the folding legs. More fun, more convenient... and worth it to spend the extra dough!
