I have had the rebounder for 2 years now and love it as much now as when I got it. It has helped see me through a weight loss of 120 pounds in the last year. I have not had to replace the bungee cords yet so I can attest to their build quality. I had used spring based rebounders prior to the Bellicon and never really liked doing the workout. This was a much better overall feeling so I could keep going and reaping the benefits. So to summarize I was 375 lbs when I bought the rebounder and it was gentle enough to allow me to work out, so I can say for anyone 375 or less it will be well worth the price.
