I personally think that this is one of the coolest USB gadgets! It is like a mini fridge you plug it into your usb port! It will cool down your drink. Although it does not cool down you drink as much as a real fridge would it is still pretty cool. I own one of these and I use it all the time. The only bad think is that you can not fit larger drinks into it. It also has LED lights inside of it. I really like it!
