Review on Grex G MAC Valve Connect Coupler by Amanda Castillo

Love it! This is my third airbrush so far and I will be getting a few more because it works so much better than the ones that come built into some high end airbrushes. First, the size of the knob that regulates the airflow is very important; Every other pen I've tried is too small making it hard to grip and comfortable to hold. Second, the area where the grip attaches to the quick release swivels allows you to place the grip anywhere: right, left, front or back - a great feature for anyone, right or left handed. Worth the price, no doubt.
