These are the best trays we have bought in years. I don't think we'll need to replace them any time soon. They are thick enough to be easily processed when molding. Things are more important than you think! This keeps them cleaner and more hygienic between uses by allowing them to dry properly. I wouldn't look any further to try and save some money. We've been through many, and these are the first "Guardians." We use them for remineralization, not whitening. I hope this helps you with your shopping. Let me know! :)
