Been playing sax for about 15 years and through this time have gone through a lot of Mouthpiece cushions, just experimenting what feels nice, which one lasts longer, the quality of it. These are by far the best I've ever used, they last a very long time, they don't flake off as others I've used have, they don't flake at all. Applies very nice and clean to the mouthpiece, once on these won't come off by themselves, actually need to peel quite a bit to get them off, especially if you messed up on the application and need to glue on another one, so you're peeling it off right away. Nothing but good things to say about them. Absolutely recommend, quality product.
