  • What a cool little tool. Cheap and accurate when used correctly!
Color: WJL-6000
I've been struggling to find a tiny leak in my HVAC system. Dye (Twice) with leak sealer failed to seal the leak and it was nowhere to be found for over a month. I decided to take a chance and get this "sniffer" to help locate the leak. Reading the reviews i was a little worried since many people stated it does not work. but after careful research and understanding that the sniffing tip of the unit is ultra-sensitive, I ended up purchasing it anyways thinking i will be very gentle with it. The tool showed up the next day, I put batteries in the unit and activate it and it seemed to perform the initial startup properly. I went to the outside unit (which I already had completely open) and started moving the probe 1/2"-1" from any object but following the copper lines, i went near every soldering point and nothing... I thought for sure the unit is not working. I went back inside and took apart the air handler cover and started following the copper lines and in 5 seconds, the tested start beeping fast as I came close to one of the valves inside the air handler. I then turned the unit off and waited a few seconds to have the air remove any leftover halogen from the tip and started it up again and went in the direction of the same area and again it started beeping. I confirmed that the leak was there by spraying some water with dish soap in it to make bubbles and BINGO! I tightened up that nut and verified with bubbles AND the sniffer that the leak was gone. All in all, the unit performed perfectly when you use it gently and I performed the test multiple times after allowing it to sit unused for a few minutes between tests. ... show more

  • Hyper sensitive
Color: WJL-6000
After reading reviews where people said it didn't work on obvious leaks (like open cans of refrigerant), I was hesitant to buy this. But I really needed to find a leak so I took the plunge. My issue is the exact opposite; no matter how low I dialed the setting, it triggered the alarm. It looked like every one of my fittings was leaking. I thought I had at least enough competency to get at least ONE of the fittings right so I immediately became suspect. I had the system evacuated and hooked up my air compressor to fill it full of air. Then got out a spray bottle with some water and dishwasher soap and started spraying fittings. After a few minutes, it was clear I had a leaking Schrader valve on the high pressure side as it was bubbling. So I replaced that and put it under vacuum a week ago; no leaks so far. I think this is a nice item and the price point can't be beat but it just didn't work for me. ... show more

  • Complete scam in waste of money
Color: WJL-6000
Complete junk. There's no fan internally to pull the freon into the sensor, I sprayed freon directly on the unit of three different types. It never once picked up anything. All it does is beep when you turn it on.Don't waste your money.
