Review on 🔌 69020 Digital Coupler by YELLOW JACKET by Matt Weber

Can anyone make a reliable vacuum gauge for the HVAC industry that works? I've tried Supco Vg64 before, it was DOA out of the box. When I got it the first thing I did was hook it up to a vacuum pump. It flowed right away. Returned it and bought a Yellow Jacket Omni vacuum gauge. At first the answer seemed impressive, small and precise. Took a day and a half and just got blocked. It turns on but never leaves the atmosphere and reads. So now, in the middle of the mini split unit, I'm trying to find another vacuum gauge.
