Product review (5 stars): Worked great out of the box
When its connected properly adjust the pressure from the CO2 tank to barely no pressure and it eliminates the foam many are complaining about. Use the hex key loosen the red knob so you can adjust the pressure to very low. It takes a few beers to get it right, don't keep adjusting it have a few and if it needs more adjusting than adjust, but once it right its great.
