Wow, you got a really good deal. They often go for $250 for a good one.
Next time you are in walmart or some similar store you might want to find one and try it out. You will understand the difference.
People who are in really good condition can do okay and not damage themselves. But even they will prefer the good ones when they have the chance to try them.
Nice to meet another bouncer. I LOVE rebounding. Smile
