The soap dispenser has two major drawbacks. 1. He has no flat bottom, where you can turn it off for filling. Fill hanging is not possible for me. 2. After about 6 months, he became leaky and lose a few drops per day.
Small disadvantages:
Little Tank Control knob slightly tilted. But you get used to it and find over time the right pressure point.
2 stars, because he he has kept at least 6 months, and was favorable. I buy a more expensive now but. :-)
