Review on Joyway Coupler Adapter Manifold Conversion by Ricardo Knight

No issues with ball bearings falling out as others have reported. The only downside is that a valve handle isn't very tight and isn't secured with a bolt, so you'll have to crimp the stem harder to tighten it if you want to. Easily connects to Fusion 2010 charging ports and will not leak. This would be obvious as previous work on the car put a stamp on the system. They also keep the residual pressure on my gauges for weeks and allow me to vent to the minimum holding charge to avoid having to vent next time I use it to keep the valve looking leak free. It looks like a needle valve, so don't overtighten or it will soon leak.
