Top critical review
Adequate, at best
on June 10, 2017
The good news first: It does reheat beverages very well!
The bad: Everything else.
1. Very poorly insulated, so either too hot, or, when unplugged, soon quite cold.
2. The lid leaks all over. Doesn't seal at all. So, if you're driving on a rough road, have it well wrapped with paper towels or napkins so you don't make a mess in your car.
3. Worst of all, the power cord is a really cheap, poorly made piece of c**p. I used it five times, and on the sixth time, it didn't work. I found a broken wire in the car plug. Very fine wire broken from a mediocre soldering job. There was nothing in the plug to prevent strain on the wires inside the plug. I was able to re-solder it, and put a knot in the cord inside the plug so that there would be no strain on the wiring inside the plug.
I would not buy this again, there are other options available. I'm sure at least one of them would be better designed and built.
