Review on Efficiently Serve with FOYO Basics Square Tempered Serving by Eduardo Locke

I bought 3 of these packaging a few months ago. They heat up well in the microwave, but then accidentally break for no apparent reason. My friend left a plate in the sink and heard it break an hour after it was last used. On the second toast today was a piece of PB toast and it broke 20 minutes after I ate. Just sat there. Super strange but do not recommend this product. It seems to contradict the laws of thermodynamics
