Query: I went through 2 in less than 2 weeks :(

I ordered this product in anticipation of my ankle surgery, and was fairly confident because I had used one 2 years ago for the same purpose and didn't have any problems. They must have started using cheaper materials, because I has 2 break on me (rubber seal ripped wide open) in less than 2 weeks. I'm not a very big person (135 lbs.) and didn't have a very big cast. Disappointing product.
