Mine works well. The trick is to put some very hot water in first, then dump it and put in your hot beverage. In my experience it keeps things blazing hot for a couple hours, hot for a couple more, and warm for a few thereafter.

There are two, perhaps unavoidable, design problems you can encounter. The first is that unless you've opened just the right amount, it's a tad splashy when it pours.

The second is that if you've got a colored one, the color will eventually start to flake off. They still look cool, but you might want to just stay with the basic aluminum color.
