I bought a bellicon because it was recommended as something that would provide me light, low impact exercise as I recovered from a bone marrow transplant. At first I was a little put back by the price, but it's been so worth it. The quality is phenomenal and the experience is just great! I use it about twice a day for 10-15 minutes and it just ... puts a pep in my step. It's as if I'm not doing exercise (although I can definitely feel the results), but rather having fun at an amusement park. I've had so much fun that my wife recently decided to trampoline too. Bouncing and lovin' it!
