Product review (2 stars): Cools tower but does not prevent foamy, warmer first pours.
It's a barely noticeable difference from not having tower cooler.  I made my own tower cooler several years ago and got rid of it because it hardly did anything.  Hoped by springing $40 this would do better on my new kegerator.  Nope.  First pour is still foamy, and warmer than later pours.  Even when I've turned on the cooler and let it run for 20 minutes before pouring.  If no one goes to the kegerator for 30 minutes, that first pour is foamier than it should be, again.

And do it's just one more thing to remember to turn on/off after using the kegerator.  And it creates a ton of condensation on the tower...dripping water on top of the kegerator.

Finally, seller provides an incredibly short hose, with a note that if you need longer you can go buy another hose yourself.  Couldn't you have provided 6"-12" more?  I have a standard kegerator and this is barely long enough to be functional and not long enough to put the motor somewhere convenient inside the fridge.

Giving 2 stars because it cools the tower, but doesn't "eliminate foamy pours" as promised.

Photos show a pour after 2 hours of continuous cooler operation.  5-6 pours in those 2 hours, this pour was after 30 minutes of no pours.  TOO foamy.
