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.

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.
