This pump works great, just like the store-bought ones that come pre-filled with foaming soap. I tried it first with about an inch of regular dish-washing soap - that was a mistake. It sort of gummed up the pump, and nothing came out. But then I filled up the rest of the jar with water, and it worked like a charm (I was probably using a 5 to 1 ratio of water to dish soap). According to online sources, the correct ratio is about 3 to 1. The length of the straw means that this pump needs to go into a standard 500ml mason jar (not the tiny ones for fancy jams, and nothing taller). If you needed it to go into a shorter jar, you could always cut the plastic straw to the correct length. I'm really pleased about this clever pump!
