The leak can happen to any regulator and is easy to fix

Good quality regulator for the money. My only complaint would be what IR charges for the mounting brackets.
If yours starts to leak around the knob, simply use a 10mm Allen key to turn the plastic top cover counterclockwise 1/8 of a turn and remove. Inside there's a spring an a plunger. Remove the plunger and clean thoroughly. Also wipe down the mating surfaces inside the regulator and remove any debris (I also used a cotton swab to clean down in the hole where the plunger sits). Apply some grease to the o-rings and reinstall.
