It is a nice mug but doesn't keep my coffee hot for more than 1 hour.

Purchased as Christmas gifts for my employees to use at work for hot coffee or to keep cold drinks cold. These mugs are very easy to use, comfortable to hold and manitain drink temperature very well. I have not found anything about this mug that fits a not so great category. All of my employees love their new mugs.

It is leak proof when tight. It's a good commuter mug for the car, but you have to unscrew it one full turn to have the correct flow, otherwise it will not be consistent and could spill around the edge of the top and miss your mouth.

The problem is the top drinking design is flawed and the twist device that fits into another sleeve is kind of an all or little design. ie. you open it slightly and don't get enough in one swallow and so you open it a bit more and it spills all over your shirt!
Other than that its durable, made of metal and also keeps liquids at desired temps for fairly long. It has a 2 7/8" diam. bottom. and is 8" tall.
