Rated 1 out of 5 by from very disappointing I bought what appears to be the only version of this available, as mine had gotten to where it stopped working. This is NOT the same one, although it's the same brand and looks the same. And of course, it would cost more to send it back than it's worth. Mfr is not giving us enough info to buy the right part.

Rated 5 out of 5 by from Good price I was afraid I would have to buy a whole new soap dispenser unit, when all I needed was the pump. I was very happy to be able to buy just the part I needed online.
