Have a couple small humidifiers in the old house, and prefer to add the 10cc/ml per gallon of tap water treatment that limits bacteria growth, and helps mitigate the negative effects of hard water on ANY humidity increasing device - be it evaporative, ultrasonic, whatever.Easy to squirt out the 10cc into a little graduated shot glass to add to the water.NO leaks around the thread area at all using a water thin product. Nice. Shame the ketchup, BBQ and mustard container sellers can't get this right. Gotta spend $8 each to get one of those that doesn't leak!Wondering if these might also be good for my home made special au jus liquid flavoring I make from scratch? No caps, completely controlled dispersion of the au jus or whatever, apple juice for marinating cooking smoked chicken, ribs, etc? LOTS of uses! Be sure what you put in there doesn't dissolve it, though. Some chemicals might.Happy buyer. A product that is what they say it is.Did I say, . NO LEAKS!? :)
