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.

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.

The cover pops off when I have hot liquid in it.

The cover does not stay on. I have an older model, and the cover is secure. This cover pops randomly off with hot liquid in it. If you don't care about the cover popping off and just want it to keep the coffee/tea hot, it works great. So I am giving it 3 stars. I also love the copper color.
