Bought one of these as a replacement for a broken sprinkler. I am completely happy with this sprinkler. I only use it as a 360 degree spay pattern. It cover ten feet in distance for my particular lawn. Easy to install. All you have to do is unscrew the old head and screw in the new. Make sure the riser is still attached. Test the spray pattern before setting you sprinklers automatically. You want to ensure no leaks are present. I will definitely buy more of these when i need them.
