Product review (3 stars): Not Bad but...
The product works pretty much as advertised IF you connect it to a computer USB port. If you connect it to a USB hub it barely gets cold.

I didn't want to run the computer all the time just to keep the drink cold so I was hoping to run it off a hub. There is a little note in the package that says it may not run correctly off a hub but no mention of it in the advertising. I think it has something to do with the fact that hubs are only spec'd to provide 100 milli Watts per USB connection and computer USB connections are supposed to provide 500 milli Watts. I still hope to get it to work from a hub...they take practically no power while a computer uses at least 100 watts.

Amazon should mention this discrepancy in their product information.
