Product review (5 stars): Does what it says it will do and then some. Reccomend.
Can't speak to it's longevity as I just got this last week, but this thing is awesome, really glad I bought it.

This actually ended up solving 2 problems for me. 1. No more foamy beer 2. Circulates air better in my kegerator- my beer and soda lines are no longer freezing (used to be a frequent and very annoying problem).

I reccomend this product. Was thinking about building my own at one point, but for just a few dollars more, and way less hassle, problem is solved.
