Review on 🌡️ AJ Tools CHIMG777 Manifold Gauge Set: Optimize Your HVAC System's Performance by Eddie Gordon

Did not claim quick couplers. I had to return it and buy another one she has or spend another $14 and wait 3 more days for her. I didn't know car systems actually had quick disconnects, but they do have threaded connections. I understand it. The manometer indicated correctly, the screw connections were tightened. I had to tighten the screws holding the handles. Without the hype about the fast connection I would have given four stars.
