Input:
Bought this strap after my recent ACL surgery for physical therapy, and I couldn't be happier with my purchase. Great quality and seems like it will hold up for quite some time. Happy to receive an instructional booklet with it as well, to do some stretches I otherwise wouldn't have known I could do with it!
I recommend this product to anyone coming out of rehab, or looking to get a little extra help while stretching.
