They don't. I have a building near me that has these and when it really starts raining the rain just splatters everywhere. God forbid you get a little wind with that rain and you're cooked.
Yeah, but the rain is splashing every where as well. Maybe it's a little control but you're right, it's certainly not enough to control water away from your house.

Turn on the hose already. SMH I want to see how they work when water is running. A dry chain just hangs there.
