Review on PIONEER Air Conditioner Ductless Charging by Jack Boldt

I bought this thing twice. First, the Schrader valve didn't push in when installed because the hole wasn't machined properly. You should have seen where he got stuck. So I returned it and bought another one. This second one required troubleshooting as the pin on the Schrader valve on the male side protruded so far into the mate that he couldn't push it down. It took me a little while to understand. But what pissed me off is that the seal on the female end got stuck in the split mini port and lost some refrigerant when removing it. That's the whole point of having a Schrader valve on the port so nothing leaks out.
