The product works well once it is correctly fit. That process is a bit hit-and-miss, and it took me a few tries to re-boil, snip, and push the heat-reactive material into the best locactions. I am on my third device, so that should say something. But I may be inclined to find a more user-friendly product given the increasing visibility of the competition.
