Product review (4 stars): Works well
Was having a lot of foaming issues with my Insignia Single Tap kegerator and after a lot of research it seemed that the cause for my foaming was a temperature difference between the kegerator and the tower. There is definitely a noticeable difference in my pours after installing the tower cooling unit. However, I still have the occasional glass (typically my first pour) which will be about half foam. Part of this may be due to the size of the hosing for the tower cooler. It is rather thick so I had to squeeze it with a good amount of force to fit it in my Kegerator tower. I think this may be preventing the air from circulating as well as it could.

Overall my pours are definitely less foamy (not perfect) and installation was pretty easy. I would definitely recommend this product, but you may want to see how wide your tower is. Otherwise you may have difficulty fitting the tube inside the tower and may not receive the best possible results.
