Review on Aupoko Retrofit Conversion Coupler Interface by Matthew Riley

This valve was a complete failure from day one. It does NOT have a standard valve core like other automatic AC valves. Peering inside the valve and preparing to use my valve core tool (to make sure the valve core wasn't loose) I could see daylight from the other side. I then used my main tool to pull it out in hopes of replacing (or reinstalling) it, and that's when I discovered it wasn't the stock kernel. I tried reinstalling/tightening it but could still see daylight through it and let air through.
