After not too much use, the hinges on these trays broke down and the lids fell off. The hinges just weren't as strong as they would need to be to make this a good product for heavy use.
Thank you for your review! This pastry tray cover is a great value. If you are concerned about the hinges, check out the Cal Mil 301-15 turn n serve gourmet cover. This cover conveniently opens with a simple twist and may better suit your needs.
