Product review (3 stars): This thing definitely helps to cool the tower of my kegerator
This thing definitely helps to cool the tower of my kegerator, but I think the promotional materials oversell it a bit.  The tower is definitely not freezing cold, and I have the unit placed right against the cold plate with the hose running all the way up to the faucet.  My first pour is colder than it was before I installed the cooler, but not a lot colder.
