Review on [2022 Upgraded]4 Way AC Manifold Gauge Set for HVAC Gauges with 5FT Hose, 3 Acme Tank Adapters, Adjustable Couplers and Can Tap - R404A R134A R22 R410A Refrigerants by James Davis

I have ordered this product twice. The first was defective with the shut off valve on the high pressure side, had a constant loud leak that wouldn't shut off. They should NOT have any quality check at all as any air pressure in the manifold would make it obvious there is a leak. I figured I was unlucky to get one of the bad ones. The second block I got didn't leak BUT this time when I opened one of the valves on the manifold it didn't open at all. Now I know I haven't had a single bad part, this product/manufacturer just doesn't know how to make a distributor that works.
