Review on Refrigerant Detector Aprvtio Rechargeable Refrigerator by Jason Fanney

I used this to find a leak in an old saltwater tank cooler I had in my garage. I replaced it because it had a leak I couldn't find. Ever since I received this device I thought it would be the perfect test. I poured about a pound of 134A gas back into the radiator and started sniffing around and within 1 minute it was confirmed that the leak was coming from a copper line that was difficult to reach by hand. I then disassembled the device and used some soapy water in a plastic bottle. The leak was of course due to a solder joint next to the compressor. So yes, it works and works well.
