I was surprised to use these: I usually spray small nozzles as fast as I can until the atomizer trips over itself and then use what came out to clean but they just won't stop spraying, I keep using randomly like a 1/4 bottle tries to see if I can screw it up. If something is so well done that I can't stop it on purpose, it gets 5 stars. They are also ideal for cleaning with hydrogen peroxide as they are darkened.
