  • Works very well, found my leaks
Style: [Basic edition/Corona Technology] CLD-100UV
I was specifically looking for a product that did the following: - used electronic method for finding leaks; I despise using soap or ultraviolet - used one of the following electronic methods: Corona; heated diode; ultrasonic - uses normal batteries (this one uses 4 AAA); some models use C batteries which I don't have a recharging system for This one uses the Corona method which means: "The instrument uses two electrodes with a current of a known baseline passing between the two electrodes. If there’s a leak present, the refrigerant will pass through the electrodes and, in turn, interfere with it (it causes a drop in the current). The drop in current will sound an alarm. The more the interference, the higher the concentration and the larger the refrigerant leak." It's a tried and true method. I was able to easily find my leaks with this product. You must let the product "heat up" for about 10 seconds before you use it. Just turn it on, and hang out for 10 seconds. Finally, the unit beeps all the time...maybe about once a second...while it's in detection mode. That might irritate you. It doesn't bother me. If it finds a leak, the beeping speeds up significantly which is easy for my ears to hear. If you don't want to hear it beep all the time which it's detecting, get the newer model that they sell. Costs a little more. Overall, I am very happy with this product. Good bye soap! ... show more

  • Believe it or not, it works!
Style: [Basic edition/Corona Technology] CLD-100UV
I bought this fully intending to return it. I double checked that I could before ordering it. When it got here I carefully opened it and saved the box. I used it to chase down a leak on a car air conditioning system. I had also put dye in the system, but it was a very slow leak and the dye wasn't telling me where the leak was. This device kept sounding off where a sensor connected to the receiver/dryer. I took the sensor out and replaced the o-ring, and now the system is fixed! My experience with cheaper devices like this tells me to take the batteries out when not in use, because the battery fumes will end up destroying the internals of the device. ... show more

  • Seem to work well
Style: [Basic edition/Corona Technology] CLD-100UV
Used this to detect where I have a leak in my MRCOOL ac unit. Found the leak using the tool - fittings not secured properly. I know professionals use much more sensitive and expensive units, but for the cost this seems good value and based on gas prices saved me either a callout charge and further wasted gas Have also used this on my car ac system which I recently refitted - confirm no leaks in the system ... show more

  • Find your Mr. Cool mini split leak
Style: [Basic edition/Corona Technology] CLD-100UV
If you're looking for a low cost option to find a leak in your AC system, this will do the job. I needed a leak detector to determine which component of my Mr. Cool mini split system has a leak. I found it with this tool within a few minutes. Easy to use, great price.

  • Sort of works
Style: [Basic edition/Corona Technology] CLD-100UV
I bought this for a garage AC I was installing. It sort of worked I guess. Gave me what I'm pretty sure was a false positive once. I probably could have done without it though.

  • Surprising good
Style: [Basic edition/Corona Technology] CLD-100UV
Unexpected that such an inexpensive sniffer works so well. Helped find an evaporator leak by sniffing the condensate on the garage floor. Amazing.

  • You get what you pay for
Style: [Basic edition/Corona Technology] CLD-100UV
I normally stay away from really cheap items, but the reviews overall were pretty good so I decided to give it a chance. We used this item twice. The first time it seemed to work ok, but the second time we noticed it was sensing on anything the tip came close to moving air. So now I do not think it actually worked the first time. We took the tip offer making sure everything was clean inside per their instructions. We could just blow near the tip and it would sound the alarm even with the sensitivity on 1. Item description said 1 year warranty. I contacted support since I was outside of my return period, but they just copied and pasted what the description said. It is like speaking to a AI chat bot. Highly disappointed in this purchase. Looks like I got suckered on another cheap "made in China" item. Do not waste your time or money. Not sure the reviews on the item are real or paid for. ... show more
