Review on JIFETOR 3 Way AC Manifold Gauge Set: HVAC Diagnostic Freon Charging Tool for Auto Household R12 R22 R404A R134A Refrigerant by John Bennett

I wasn't a big fan of pressure gauges because I never used them and was a little afraid to use them. This set takes the guesswork out. Very easy to use and the quick connectors only fit the intended connector, basically you can't go wrong. I highly recommend everyone to have a set and for this price why not. There are many instructional videos if you need further help using it.
