Use this as my coffee mug. Coffee stays hot for hours and is actually leak proof which is what i was looking for. I have noticed that after only several uses and cleans, the bottom has slightly warped and now does not fully sit flat and wobbles which is very upsetting given how expensive it was.
I received as gift. Beautiful but not functional. Lid opening no place for your nose. lol. And it opens in large area so you pour it in yourself. Needs drink ledge.
