I bought this cause of th...e great reviews. After using it myself I see why, I found my leak in less than a minute. After not being able to find it at all with dyed leak detection r134a. I so glad I bought this detector, super easy to use and no need to use those irritating uv glasses and uv light . This product is definitely a time saver and simple operation. Five star for sure *****

not the fanciest tool in the box but it does work. I h...ad a can of freon still connected to a valve. So I decided to give it a try, the can have been sitting around for a while so nothing was detected. I opened valve and it started tone change. Shut valve off and the residue still alerted tester. So yes I recommend it . On & off knob was loose . I had to snugg it up. UPDATE NOT TOO SURE ANYMORE. So I just put tester through the test. And I'm not positive if it works as needed, if touch a part with tip it will beep louder, if you touch your arm with it beeps louder, if you touch a wall ,guess what,beeps louder

I have only used it a couple times. Seems to work well. I... need more usage to get a better idea of it's capabilities. My old Freon detector costs 12 times what this one cost. it uses (4) AAA batteries which I like. My old detector is rechargeable which can be a problem when it goes dead.

Works well, sensitivity appears to work. The directions indicate a siren sound when the refrigerant is identified, however the sound just clicks faster. still it changes sound and can be used.

Can't believe it! It works better than a $300+ "professi...onal" unit I had before. I was able not only find a small leak but also pinpoint it to the EXACT location .2" away from from the likely source - flange seal. It turned out to be a micro crack in the pipe. Thanks!
