Are you still annoyed about the problem that it's inconvenient to dry your hands after washing?
This design is here to help you solve it. This product's switch of running water can be open or closed by testing the heat of your hands and it makes it easy to wash. After washing, all you need to do is just to turn the switch slightly, then water stops running and the winds begin blowing. You can leave with your hands dryed.
