Review on 🔧 Wadoy R410A Valve Core Remover & Installer Tool for HVAC Systems by Michael Bressler

Screw the tool to the fluid port and was able to start pulling the stem out, felt resistance, tried to pull the stem to remove the stem to close the valve on tool, but the handle got in the way. When I went to make sure the tool was screwed in, the whole tool fell apart. Many P-22s lost. Poor design as the entire tool is only held together by a very thin metal o-ring in a small groove. Paid about $30 with overnight delivery. I'll try to return the money or at least replace the unit in hopes it's defective, but who knows?
