Works
I bought this to test the high side of a refrigerator repair. I bought it mainly for the adapter part, the gauge and hose were an inexpensive bonus. Worls nicely. Easy to read dial.

Works great
I used it to do a 24hr pressures test on a mini split system. I was able to reinstall the cover overnight with the gage in place. It worked well and held 530psi for the whole test. Was easier than using a full hvac rig.

Yellowjacket good quality if a little spendy
Yellowjacket stuff always good, you know it will work exactly as advertised, fittings will be quality etc, etc. But you do pay a premium for that.

Yellow Jacket refrigerant gauge
Worked as I expected a Yellow Jacket gauge to work. I like the short hose. I use it on small refrigerant systems so that I do not lose much freon. It works for that purpose.
