Where has this been all my life. I have to drink slowly and my coffee always cools off before I finish. With this I can keep it hot for hours. It looks cool and is easy to use

Purchased for a gift. Recipient was impressed with how easy it was to use and it maintains desired temperature (internal battery). Temperature control is on the cup eliminating the need to control through an app. If you do get busy and forget your coffee/tea it reheats very quickly. Several of her friends have purchased on her recommendation.

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.
