When you open the faucet to brush your teeth, the time you waste on squeezing toothpaste or scrub- bing soap is the time that water is wasted.
ONFF can solve this problem. Inspired by the soda machine, the function of the faucet is press- ing for the release of water, and let go to make it stop flowing. Opening and closing the water flow any time, and conserving water every second.
