Great product, leaky sprayer
The leak detector liquid is great. The yellow bubbles appear quickly even on small leaks you can't hear. One star off for the leaky spray bottle though. The sprayer leaks in use and during transportation, not enough to pool up but enough to be annoying. Wear nitrile gloves for use, store on a tray, and carry in a plastic bag.

A/C leaks made easier with this.
I purchased this product with hopes it would help me find a very hard to find leak. With my detector and this spray it was found. 💪

This will find your leak
I tried soapy water I tried just soap. I tried big blue. Finally I over inflated my 20 foot RHIB and sprayed it in sections. Voila. A little tiny llean near the bottom started bubbling. I could have jumped for joy after spending a week trying to find that micro leak. The leak was so small that once the presser started getting low I couldn’t see the leak. So make sure to over inflate to find the leak.

Used as a alternative to regular soap
It didn't work any differently than dawn dish soap but it was at least more visible than dawn dish soap. Not a bad product by any means.
