Query: Lid Melted to Base

I used this twice. The first time the hard cooked eggs were great. The second time the lid melted to the base and it had to be pried off. I have emailed the seller who's policy is not to allow returns for used or opened items. I also emailed Oster to let them know although they should know - based on other reviews, this has happened before. I should have paid more attention to the negative reviews!
