These pumps work great with 1 liter bottles of Wella Shampoo and Conditioner. I'm not sure why other people had so many problems with them. The box they came in had instructions printed on the side. I followed them to unscrew and open the spout. I screwed pumps into bottles and even wasted some of the product to see if I would have some of the problems that others had. I'm happy to say that they worked very well.
