Product review (4 stars): a must have
If you have a non commercial kegerator, you must have this. It works very well. Fixed the foam first pour issue completely. I have the liquid temp of my beer set at 38. Before I installed this the tower felt warm, now it feels very cold. I inserted a wire probe in the tower and with this installed, it reads around 43-44. For the price, does not make since to build on yourself.
