Although the overall quality and usability are very good, the quality of the joint part is fatal. It is a mere item. I use it by attaching it to an ordinary faucet, but even if I fasten the hose joint connecting the faucet and the hose, I can get out of spot. If you do not tighten the joint attached to the main body side every time, it leaks. Is it a matter of plastic quality? I do not know the cause. If you do not close the faucet after using it, it will be tough to escape without permission.
