The ember mug is great; I got one as a swag item and thought it was silly, but ended up using it every day. Sadly the ember mug is now much more than $100, and the coaster on mine has broken twice, so I just gave up on it. One of these days I will solder on new pogo pins.
How long does it take you to normally drink a mug? I've been interested in it but I find that I tend to drink a coffee quickly before it gets too cold, and with tea I actually enjoy the change in taste as it cools
