Review on Ceramic 🛡️ Reusable Contamination Shield by Adam Rogers

I love coffee to stay hot. They do the job well but don't exactly fit the cup they fit in. In other words, the lids could either be rubberized or made slightly larger with a deeper rim to fit the average coffee mug they were "designed" for. They are "slightly smaller" than average so they fall down a little on each cup, allowing vapors that would otherwise be trapped to escape too quickly, keeping the coffee/drink hotter for longer. I would like to rate them higher as I was looking for this type of mug lids. But unfortunately I have to be careful as they don't fit in every cup (and I've tried all mine) and they can detach from the cup when you move them.
