Product review (5 stars): Quiet and effective. Good value.
Works really well. The fan is quiet and the thin cord just runs out the front on the side by the hinge. This product keeps the beer line in the tower cold and helps keep the foam down (I noticed it also helped to turn my CO2 regulator down to about 6 or 7). Nice product. Wish the hose was a bit smaller in diameter and a few inches longer, since my tower is only 2.5" diameter, but it does its job. I let it run constantly whenever there's a keg in there. This along with an insulating sleeve on the outside of the tower makes a great add-on to any kegerator without a tower cooler. Good value. No need to spend $70 or more on something like this.
