I liked it so much that I got one for my wife and one for my sister. (I would have bought one for my brother, but he said he didn't want one.}
I got an Ember mug as a gift a few years ago.
It's a heated mug you can use to keep your coffee warm so you can drink at your leisure, rather than trying to finish before it cools off too much.
It is fantastic. I can now keep my coffee on my desk while I work, taking a sip every now and then, knowing that it is still going to be nice and hot.
