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).

When you remove the wrapper you have no idea what is in bottle is anymore.
When you remove the wrapper you have no idea what is in bottle is anymore. The product has a plastic wrapper that holds the lid on and keeps it from spilling while being transported. When you take this wrapper off all description of the contents of the bottle are gone. You'll need a felt tip pen to mark the bottle so you know what it is, in the future. The product itself is fine, but the packaging could stand some improvement.
