My only complaint is that the cup doesn't come with a replacement rubber/soft plastic piece for the lid. We accidentally lost it in the garbage disposal and it most likely got eaten by it the next time we ran it after dropping it down there. Now heating will not function optimally and I can't drink it with the lid on without spilling everything.

This does NOT hold 12 ounces

This does hold heat. It stays pretty hot, even when I don't put the lid on it. Which I don't like the lid. But my issue is it is so small. It says it holds 12 ounces. It does not. I can only brew 8 ounces in it and a little room for cream. And that fills it to the TOP. I can usually drink a 8 ounce cup of coffee a lot faster than a 12. So it would of been more beneficial if it had been a true 12 ounce cup size. Disappointed in the small cup size.

ISSUES WITH BRONZE VERSIONS, not black ones.

I love my IonMugs, but have had issues with my bronze ones. I have two and both of the charging coasters have melted around the prongs, making the prongs start to sink into their plate. Also, one of the lids bronze coating has chipped. I have had zero issues with black mugs and their charging coasters and do recommend these.
