This product comes with a nice dabber, so that is a plus. Some other products expect you to supply your own. It has a light viscosity, which I find better than the water-like solutions in some other products expect you. I cannot tell you if it is effective, since I haven’t yet had a failed joint. I will modify this review once it gives me a positive test.

I have tested a lot of pressure joints in my day and this is just way easier than mixing soapy water. You get everything you need and can close it up for next time. Maybe I'm getting lazy later in life but I'm not going back to the old way. This blows bubbles perfectly and this bottle will last me a long time.

The brush option is great for certain leak checks where the spray is not needed

pinpointed my small refrigerant leak. Fixed it myself, recharged the mini-split myself, saved $hundreds.

The product is easy to apply and great at finding leaks. Shows small leaks you just cannot find using home made soapy water. As reported by others the product leaked in shipping, but I only lost a small amount. You should considering purchasing from local store, if available in your area.
