Locking Mechanism Breaks
I've had this pan for about a year but I've only used it a handful of times. I went to use it recently and the locking mechanism wouldn't hold the bottom in place no matter how much I messed with it. I tried to force it shut, thought it held, and discovered the hard way that it didn't keep (when I pulled the pan from the oven and my entire pie hit the floor when the bottom fell out.)
