Query: Don't Buy These

I bought a medium resistance and a heavy resistance band. I broke the medium resistance band almost immediately. The tubing snapped right at the handle on one end. I threw it away and started using the heavy band. After a couple of months the tubing snapped at one end just like the first band. I tied knots in the tubing to keep it from pulling back through the handle and continued using it. A couple of weeks later the other end of the tubing broke. I tied knots in that end too. Now I have a short VERY high resistance band which is working fine so far. I am not a very strong guy, so these bands must be for real wimps. I do like the really comfortable handles.
