Why settle for just USB chilling or USB warming when you can have two for the price of one? The cooling keeps your drinks down to 11 degrees Celsius (51.8 F) and warms them up to 53 degrees Celcius (127.4 F). Pretty impressive when you compare it to the standalone units.
Not a bad bargain for $24. Just don't accidentally rest your elbow on it.
