My wife had one of the custom made devices made several years ago. It wore out after a few years. She now uses the cheaper things from Wal-mart and says they work just fine. She has also tried the type that need to be heated in boiling water to soften and then put in your mouth to form them. She claims the even cheaper ones work just as well.
