Review on GooMeng R410A R22 Remover Installer by John Kennedy

It worked once but fell apart on second use. It is dangerous to remove the valve core as the head that engages the valve core is threaded and you think you have loosened the valve core but you just unscrewed the head from the stem. It's not the worst yet. The 1/4" knurled knob that screws onto the condenser valves caught my hand. There's some sort of wire shackle that's supposed to hold it together, but there isn't one. I threw it in the trash.
