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

ok, for those who didn't read the instructions... this cup is amazing, I'm on month two with it, no issues bottom of your cup, hold button until lights flash, choose your temp or whether to put it to sleep... don't forget to do that after your finished... this will keep your drink hot, so hot, you'll need lip balm for the burn if you aren't careful about one hour off charger, then recharge, repeat. my process is simple, fill, drink, repeat. I work up to 12 hours at my office, so do purchase if you are tied to a desk

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.
