Bests & Worsts Reviews from Amazon

I use this minitrampoline for cardio exercise (jogging in place) when the outside temperature, or my knees, tell me not to run. This is my second mini-trampoline. The first one used springs instead of the elastic bands. The spring design sucked. I trained for a marathon and put many hours on it. I decided it was unsafe to use after the 4th spring broke (from fatigue or friction - probably a combination of both). I bought replacement springs and discovered one needs a special tool or superhuman strength to put them on. That's when I discovered the design was changed to incorporate bands, replacing the springs. Much better. I happily purchased the newly designed unit for which this review is written. I have put many many hours on this new "band" unit and so far no problems.
