it does what it supposed to do.
it cools to around 5-10 degrees.
in the summer it is perfect because every liquid i drink gets heated but with this cooler it gets cool and stays that way.
there is no extra electricity cost because it uses that of the computer.
poor construct, the cooling fan unerneath is open so it will suck up dust if you let it.
there is no fit for a bigger beercan or such.
