I'm a slow coffee drinker. I'm not the type to sit down finish a cup in 10-20 minutes then move on.
After having the Ember Mug for about a year now, I can't imagine being without it. The idea of having to go back and forth to the microwave, jacking the taste up, etc. seems rediculous now.
So, for any slow coffee drinkers that always has a cup nearby to sip, ocassionally. I highly recommend it, regardless of the seemingly high price.
