I think the main reason they're not selling is that people just don't realize how cool these things are. To the uninitiated it looks just like a bog standard Peltier type electric cooler. If you know anything about anything, you know that those things consume obscene amounts of power. It's not until you understand that this thing is not only much more energy efficient than a Peltier type cooler, but quite a bit more efficient than a normal Rankine compressor fridge that the unit (and the price) make sense.

If you're living on 12V and want a fridge, you want one of these puppies.

Zoom off to the Coleman factory outlet and grab them while they last!
