With the Quooker Fusion Round Black, you can easily get boiling water. The faucet has double-push-turn controls. This means that you have to pump 2 times and get boiling water directly from the faucet when you open the faucet. That's useful, as this child safety lock prevents hot water from accidentally coming out of the faucet. You can also use it as a mixer faucet for warm and cold water. You can easily do this with the handle on the side. The spout of the faucet is double-walled and doesn't get hot because of this. That way, you won't burn your hands.
