Since I recommend using them for jogging, I've been asked about how to pick the best rebounder. I have recommended looking at the springs to make sure that they are big and, ideally, tapered at the ends. I say this from experience as I am on my third rebounder. The first one's springs started snapping after about a month's use and the second's started snapping after about three months. The third one has not given me any problems at all and it has big, meaty springs that taper slightly at the ends.

I have since found my manual for my latest rebounder and have discovered that while the other two were designed for jogging, this one is designed for jumping. I suspect, therefore, that jogging rebounders are not built as well as ones for jumping.

It might simply be that anyone buying one for jumping may be considered a more 'serious' user than someone buying it just for jogging. I have a theory that quite a bit of exercise equipment isn't designed to last all that long but that the manufacturers know that few will complain because most equipment ends up gathering dust after a month or so.

Anyway, if you are able to examine the rebounder and its manual before buying, look for the ones meant for jumping/bouncing exercises.
