Review: They actually work great, and come with a blacklight - These things are great and well worth $25 if you are a "do it yourselfer". This is the second one I bought, because the first is in another state. The beeper will find freon, even on R1234yf, as I tested it with the can. It found the leak on my R134 on my Toyota last year. And, using the blacklight, just found the leak on my GMC Sierra, which comes precharged with fluorescent dye. (below) Didn't expect much for the cost, but they really work.
Review: Simple to use, inexpensive, and works. - I ordered this product at the beginning of an auto AC DIY project that went on for months, and didn't get around to actually using it for awhile, but by the time I did, I found that it worked great, and was well worth the price I paid for it. Specifically, it helped me confirm that the valves on both high and low AC service ports were leaking, and that I needed to replace the cores in both valves. It subsequently helped me to confirm that my core replacements worked, and sealed the leaks I was previously detecting. Both the detection and sensitivity functions worked fine for me, and they should for you too, as long as you follow the instructions and don't expect this simple gizmo to perform like some kind of lab grade precision tool. When searching for leaks in unknown locations, the instructions suggest starting with the highest sensitivity level, then gradually decreasing it until you've pinpointed the exact location of the leak. I did the opposite, because I was testing for leakage from two known locations (AC service port valves) ... in other words, I started with the lowest sensitivity, put the tip as close to the valve opening as I could without touching it, and then worked my way up to gauge the severity of the leak. I got a few false alarms in ambient air at the highest sensitivity setting (knob turned until stopped), but wasn't upset about that. Just turned off to clear/reset the internal electronics, started the sequence again at a slightly lower sensitivity setting, and it worked fine. No false alarms when I backed the knob off a little from max rotation, which I see as "normal" for a simple device like this. For example, the control knob just isn't that sophisticated ... it's the same as a combination power/volume control dial on a radio, which probably gets pretty sketchy when it's controlling the "sensitivity" of something as delicate as an electronic gas detecting sensor. This is a BASIC refrigerant leak detector that worked as advertised for me, for a very reasonable cost. Very satisfied.

## Questions & Answers

**Q: The sensor seems not to work, how can I detect by myself?**
A: Second application, first time it worked well, but now it beeps two times a second, yet doesn’t detect even a direct stream of r-22 vapor. ??

**Q: Will this work on a car freon?**
A: yes

**Q: Does this detect the smell of Freon refrigerant etc.? Or does it alert you for a leak if it feels air blowing on the sensor? Thank you**
A: I am currently a student at a local college working on my last semester of refrigeration and air conditioning technology, I have used this sensor to detect R-22 and R-134a leaks and verified it with a much more expensive sensor.  It works for these two refrigerants and yes, it detects the gas not just air.  I also use soap bubbles once I have verified the location of the leaks.  Best $20.00 I ever spent.

**Q: Will this unit detect R421a?**
A: The product packaging specifically indicates it will detect R134a, R410a, R12, R22 and R600a (and I've only used mine for R134a), but I'm guessing it'll work with pretty much any commonly used CFC-based refrigerant.

### ⭐⭐⭐⭐ Seems to work, originally thought it did not
*by D***S on June 10, 2018*

So I thought the unit didn't work but it turned out I had 1 of the 4 batteries in backwards. My bad. Amazingly the unit still blinks the LED mostly green even with one of the batteries backwards, just doesn't detect refrigerant. With the batteries properly installed I can spray a small burst of HFC 152a into a cabinet and then the probe detects the refrigerant whenever it's brought near the cabinet. Though after about a minute the refrigerant has dissipated enough that it can no longer be detected (in a mostly closed cabinet) so the sensitivity may not be as high as advertised. original 1 star review *The unit doesn't wnework. The unit powers up properly with the green LED blinking. But there is no change when exposed to refrigerant, even spraying HFC 152a directly at the probe. Tested it outside with no refrigerant and also in the garage, spraying HFC 152a, at different sensitivity levels. Same blinking and beeping in all cases. Possibly it's just a bad unit. I may try another one and if that works I'll update this review.
