I love 1/4 turn taps - you can see at a glance if they are off and
people (like me) don't turn them off to blacksmith's arm strength just
to be sure. and the kids don't leave them dripping (they might leave
them on - but if they do turn them off, they do it properly).

Trouble is that if they're half on, and you've forgotten which way
they go, you may end up getting soaked when trying to turn them off.
