I purchased this a few months back.
Wouldn't buy it again, it keeps liquid at lukewarm at best… that's even when the lid is on, so don't expect it to be hot.

Previously marketed as the Tzumi IonMug. I bought and returned also. It did not perform as advertised, but it did slow down the cooling so for some it might be enough

Agreed bought it a few months ago and it's horrible. I have an ember and wanted a backup for work but nothing like it.

That's funny, mine gets everything way too hot even on the lowest setting.
