I just bought it for the novelty of having an automatic soap dispenser and now love it. I use a sponge to wash anything that doesn’t go in the dishwasher and got tired of turning the Dawn bottle upside down to get soap on the sponge. This works great and lets you keep one hand free instead of needing to use both any time the sponge needs more soap.
Although the convenience of a motion sensor to drive the soap dispensing mechanism seems on its face to be logical, the normal positioning of a pump with this intended function places it in a location that ends up dispensing soap all the time (every time there is motion nearby). Would be easy to put a second requisite sensor that must be triggered (say in the top) to prevent accidental dispensing.
It works perfectly. I am using it for dishwashing liquid and I wave a sponge underneath to release the soap. It also works if I want to add soap directly to a pot in the sink, I just need to keep my hand close to the dispenser so the soap falls directly into the sink.
