So I went ahead and E-mailed the company.......
Thanks for your inquiry.
The DownSafe Descender is designed for a single use. However, after a fall, the unit can be returned to us, and for a fee of $24.95 plus shipping, we will refurbish, re-pack, and return it, so that you can use it again without having to buy another new unit.
If you need additional information, please let us know.
I'll probably buy one for the peace of mind.....hopefully it lives up to expectations.....
