Great product for reassurance!
Smelled gas from the stove and had a technician come assess; he used something similar to this product and I didn’t fully trust his assessment as I swear I thought I saw some bubbling! So after he left, I Bought this item to do my own testing! It arrived quickly and gave me the reassurance I needed that my stove did not have a gas leak! Quick tip for using: The item comes with an applicator; I noticed that the liquid has some bubbles just from shipping so I let it sit for a bit before I applied it, as when I first applied it the natural bubbles from shipping made me believe there was a leak- just a heads up! (FYI the way I pushed some of the small bubbles out quicker was by gently banging the bottom of the item on the counter a few times!) enjoy!

Excellent leak detector.
Excellent. Made it easy to find a very minor leak in a line set of a 3-head mini-split system. Well worth the money. No issues with product leakage during shipping (as reported by some others).

I purchased these bubbles based on videos that I saw on YouTube that recommended them for testing leaks on a mini split lineset. Got my AC recharged last summer and it was out of refrigerant within 8 months. I pressurized the system with Nitrogen, then testing all four connections. I used the enclosed cotton dabber to apply the bubbles to the connections. Within a few seconds, i found the leak. The bubbles stay on the fitting for at least 30 mins. I also used the bubbles on a tire valve stem and found a slow leak that was causing my tire to go flat.

Very useful for detecting gas leaks, much better than the old soap and water method. Very good for detecting slow leaks. It is nice that it includes the applicator to brush it on gas connections.
