Review on 🚀 Grit Performance Heavy Duty Tire Pressure Gauge (0-60 PSI) with Custom Foam Case, Chrome Caps & Valve Core Repair Tool - Rapid Air Pressure Gauge, Ideal for Offroad 4x4 Tires, Includes Tire Deflators and Other Accessories by Len Chandler

Works as described HOWEVER you must follow these instructions once you screw the air release valve into the valve stem you must turn the stem clockwise to engage the valve core and then once it is engaged , rotate the stem counterclockwise. to unscrew the valve core. Put your finger on and prevent the stem from popping out all the time by continuing to turn the stem counter-clockwise so the valve core definitely comes free and out of the valve stem. Trust me it works and it takes a few tries to get the hang of it. Make sure it's twisted, once you pull it out you can control a little air or a good product, and it also comes with a decent storage box.
