Cool or Warm Cans, USB style

I have seen a lot of dumb USB powered devices. A lot of them. However, I found the USB Can Cooler and Warmer to be easily one of the most useful. After all, nothing is worse than warm soda.
I am assuming that this device has the power to keep your can cool, and probably does not chill your soda cans in a matter of minutes. There are other devices for that. However, if you want a soda can to stay cool, then Brando's newest is for you. Apparently, it even has a two-way switch that will not only cool your can, but warm them too. Don't ask me why you want it warm, but I'm sure you can think of some other uses for that, maybe.
Well, check it out for about $32 USD, see how it works for you.
