A New Kind of Faucet with a Little Twist

I can see it get stuck and then you need to get a wrench or pliers to get it moving again. Agree on cool design but leaves a lot ot go wrong.

except if the water is too hot you have to put your hand under the stream to adjust the temperature, resulting in burnt hands.

Nice idea, looks cool, but ultimately the problem it solves is not as important as being able to rinse off your hands wthout burning them.
