Review on 🌡️ Aupoko R134A AC Refrigerant Charge Hose with Pressure Gauge - 1/2’’ Acme Can Opener Tap Dispensing Valve - Ideal for Car AC Air Conditioning Refrigerant Recharge by Matthew Henderson

I bought this because my other faucet doesn't have a pressure gauge. I was thrilled when I plugged it in and got a pressure reading, but when I tried to dose the freon it didn't work. I'm afraid if I disconnect the attached spray can the freon will just splatter everywhere. Now I have to use my old faucet dispenser to add the freon and use that with the pressure gauge still attached and the full freon canister just to measure the pressure. Unfortunately I have a can of freon that I can't use and I had to go to the store and buy more. I wouldn't buy this again.
