Review on LotFancy Freon Leak Detector: Ultimate HVAC Refrigerant Gas Leakage Tester for Home & Professional Use - CFCs, HCFCs, HFCs, R134a R1234yf R410a R22 R11 Compatible, High Accuracy & Indicator Light by Devin Jirsa

Hello everyone, for the record, I work with all types of freon, I did not find a leak, I painted everything and nothing, I bought this device and laugh, it's small and looks nice cheap but let me tell you i was. Not correct. I put the batteries in order, turned it on, looked at the lines, boom, here it is, I'm not kidding, I found less than a minute. I recommend to everyone who works with freon. When you first start, turn it on, and when the beep starts, wave it in the air to give you the perfect spot where the leak is then the beep will start to get fast, bam I had it, a little hole in the line, I paid for it myself the first time I used it, try it, you won't regret it.
