This stuff is very easy to spot leaks instead of wasting time on a job or project looking for soap and water bubbles. It seems like a lot for a green spray bottle, but trust me it will save you money because you won't be wasting argon, carbon dioxide, etc. because you've missed leaks. Another great thing is that if you find you have a leak and spray it once or even twice, it keeps bubbling for a while instead of spraying constantly over and over again.
