## Customer Reviews

### ⭐⭐⭐⭐⭐ bubbles like crazy when a leak is found.
*by S***W on April 22, 2025*

this stuff works amazing, I bought it for checking for refrigerant leaks on cars & it works great, it doesn't bubble up all over like soapy water, but when there is a refrigerant or air leak, it bubbles like crazy! there is no question where the leak comes from! definitely will buy more when I run out. it glows in a black light also which is very nice also!

### ⭐⭐⭐⭐⭐ Great at detecting small gas leaks.
*by C***H on June 18, 2025*

Great at detecting small gas leaks. The florescent color makes it easy to see small bubbles, and the spray bottle works well.

### ⭐⭐⭐⭐⭐ Buy it, it’s worth it.
*by F***. on May 16, 2025*

The media could not be loaded. Great product, shipping for a gallon is a bit high. Truck driver called to fix an air leak. He tells me it’s somewhere in the transmission and nobody can find it. I told him give me a minute, let me try this spray. Found the leak and it wasn’t in the transmission!As you can see in the video, he told me I’m the third guy checking and the only one that found the leak. Simple things like this It’s great for, I do wish people would leave good reviews with videos or pictures when you get a good product. As much as they leave a bad video of damaged shipping, that has nothing to do with the product.
