Sounds great on paper. In practice? 51 degrees ain't cold enough and 127 ain't hot enough. Waste of $$$. Thanks ThinkGeek.

Well, 127 is pretty hot for coffee, I know that much. The 53 doesn't seem very low but then, I don't know what the temperature of my Pepsi is right out of the fridge anyway. Someone should test that.

I bought something similar(just a regular USB drink warmer) as a secret Santa gift for my office Xmas party. We were supposed to spend $20 and my gift cost $21.40 so I figured I was being good and getting something original. Too bad the non-geeks I work with had no clue what I bought. The jeers of my coworkers chanting, "oh that had to have only cost 5 bucks" has totally reinforced my plan to buy 20 bucks worth of crap at the dollar store next year.

I'm not an electrical engineer, but wouldn't plugging in a high wattage device like a HEATER just add un-necessary heat and strain to your delicate and expensive computer? So you can have your drink slightly warmer or cooler, at the cost that your Powerbook may fail a few months earlier. People, the USB port on your computer is not the cigarette lighter on your car!

I got the USB drink cooler for Christmas, www.coolitsystems.com and I have to say the little bugger gets pretty cold...but it falls short from keeping my actual drink cold. The only part of the can that stays cold is about the bottom half inch or so, not great, but better than nothing.

Um...it runs off of USB and uses a Peltier. It may pull some current, but it's not a heater. One side will warm up, and the other size will cool. The switch just reverses which side does what. I bought this for my mom, and I was a little taken aback by the size of the heatsink (entire area under plastic), but it makes sense since the underside is going to be hot while the top is cooling.
