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

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.

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.
