Product review (5 stars): Perfect Pour Reached
This really fixed my foaming issues.  I would get lots of foam on pours that were any more then 15 mins apart.  I thought that was too much to be a tower cooling issue, but after meticulously balancing my lines and pressure, this was the next step.  I tried building my own but it barely pushed any air, so I decided to just bite the bullet and buy this.  It was rather worth it.  Now my first pour is perfect 24/7.
