Review on 🌡 BELEY Digital Manifold HVAC System Gauge Set with High-Precision Vacuum Pressure Temperature Leakage Tester Diagnostic Meter Kit for Testing and Maintaining Air Conditioners and Refrigerators by Billy Dotie

I received this unit a few weeks ago. I used it today and none of the hoses work. I read other reviews and knew that high and low hose applications would require quick disconnects to work with automotive applications so I leave them as needed, but even the umbilical hose is 1/4" instead of 1/2" so it doesn't fit those Standard 134a. tank. Which isn't a big deal. I took the $20 converters for it, but I went to turn on the display and it doesn't turn on. I've tried different brands of batteries and tested them to make sure they're good, but no matter what I tried, I couldn't turn on the display. I don't want to return this item because I'm excited about the possibilities for me, but there is no contact information or a way to contact support to resolve the issue. I hope to get an answer from the supplier within the next 5 days, otherwise I have to send it back.
