Review on BELEY Digital HVAC Manifold Gauge Set with High-Precision Vacuum Pressure 🌡️ Temperature Leakage Testing, Diagnostic Meter Kit for Efficient Air-Conditioner and Refrigerator Maintenance by Eric Aulia

At first everything seemed to work fine. After adjusting the load to read some of the hardware gauges it will show 50psi after a second and then 200+psi. I re-zeroed it, plugged it back in and started having trouble again and when I unplugged the hoses it still read +-40+ psi which means how wrong the reading already is. I checked that with my calibrated yellow case dial gauges. I thought the price was too good to be true for digital gauges and it looks like I was right. I just made a return request. It was worth trying, but as a seasoned HVAC technician, my experience wasn't very good. Updated after they returned them 3 weeks ago and the seller received them 15 days ago I still haven't received a refund. Contacted Revain a to z support today and they are working on it. In addition, the seller does not offer return costs. So it costs me 17.45 to send this junk back. I would definitely not buy anything from this seller. Worst experience I've had buying here. Also, I see tons of reviews people give about this product before actually using it. Be sure to check the accuracy of the sensors. Mine were far away and jumping all over the place.
