Review on Enhanced Aprvtio Refrigerant Leak Detector: LED Light, Halogen Leak Tester for HVAC Systems (R22 R410A R134A R1234YF), CFCs, HCFCs, HFCs - WJL-6000PRO 2021 Upgrade by Amador Buckenmeyer

The detector arrived quickly and well packaged. Easy to understand instructions. Beautiful storage bag made of nylon fabric. Bought to find leaks in ice machines using Freon 404. There was a leak and we had to replace 23lbs at $60 per #. We were able to find and replace the leaking fan switch and super hose. Then fill the entire system and leak test to make sure there are no leaks. I recommend and buy again.
