Query: Good idea, needs better construction

I like the idea of silicone and glass on the bottom. It's especially nice to be able to cut your cake without the risk of removing the bottom. The silicone unfortunately ripped and got stuck to the glass on the bottom the first time I tried to use it so the seal is no longer functional, but Amazon provided a full refund and I didn't even need to return it so great customer service and it didn't inconvenience me. If that didn't happen to the pan, it would have worked perfectly.
