1) We get requests for them.
2) I'd love to push them more as a more exclusive (and more expensive) product but I am afraid to because of the problems we have with them.
3) I personally prefer them in my yard. I live in a nice subdivision and we are known for having the nicest landscape in the neighborhood. I try hard to make our landscape outstanding. And these mutli stream rotors look the coolest. I know that sounds like a rediculous reason to use them but it's true. When they are on, they stand out from other, more common sprinkler heads.
