“Seems solid. Has a very wide spray area but as 90% of the water goes out to the extreme of coverage it leaves the inner area fairly dry. There was one hole on the stem of each arm to wet inside the circle but it delivers very little. So you end up with a ring of water and then it's dry back to the sprinkler. If the arc is out over the edge of the roof then you still have a dry roof. I'm going to still use them but will need to overlap quite a bit more than advertised and I'll have to keep using my old ones which dont work as well but at least they spread more evenly when they do work.”
