They didn't work.
I filled both of these up and neither one of them worked. The tops were hard to remove and the plastic bent easily when trying to remove the tops so that I could see what was wrong with it. The plungers were there but never moved to dispense the oil. I tried to replace the tops to make sure it wasn't just a fluke. But it still didn't work. I had to just move on a buy different airless pump containers.
