There are lots of rebounders; but only one Cellerciser®.
There are many brands of rebounders available.. some even look identical to the Cellerciser® (only from a distance!). With just a little looking, you’ll see the old adage “you get what you pay for” to ring especially true with rebounders. Simply put, units under $100 are dangerous. Do NOT use them. Units that cost a bit more will feel more substantial and sturdy – but the inferior quality shows through in the details (cracked composite frames, sagging mats, rusted springs, chipped paint). G-Force Health has tested every rebounder on the market… and only trusts Cellerciser®.
