Simple but effective product
This is not your typical soapy water. This is some thick stuff. Normally I use soapy water or some type of cleaner and wanted something more sensitive. While this takes a little time for stuff to show, this is quite good at showing the micro leaks. I’m very pleased at this for the price as this helps finding a tiny leak when a leak detector can’t find it when it’s a little breezy.

A little goes a long way
Does what you'd expect. Helped me find a really small leak in a welding setup. A little goes a long way.

Great product for finding leaks, but
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.

Works Great At Finding Small Leaks
I was a bit sceptical when I first heard of this. However I've used it to find small leaks on AC systems under pressure and it works great. I'm a mechanic and the magnitude of my work is motor vehicles which can be very difficult to source small leaks due to component location, obstructions, and plumbing design of systems. Recently, it saved me on a MINI Cooper which I was suspecting an evaporator on, until I used this and it revealed a microscopic pinprick on one of the hoses to the compressor which would only leak when the hose was stressed at times. Soapy water didn't do it for me, but this stuff foams and bubbles up real good. I was able to catch it. Thinking of buying their spray solution as well.

Lots more fun than mixing up Dawn
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.
