Review on 🔧 Wadoy R410A Valve Core Remover & Installer Tool for HVAC Systems by Mark Colbert

I had the entire AC system loaded with R410, it cooled down well, I tried to install the valve core and the tool exploded in my hands (less than 300psi) burning my hands and losing that entire coolant. When the package arrived it was sealed with tape so I could tell it had been used/returned. Very disappointed and very angry. Now I have to buy a different brand tool and wait for it to be sent because that tool was complete rubbish. Do not take any risks.
