Somebody please kick me if I ever buy another Gilmour pulsating type sprinkler. This sprinkler is relatively easy to set up, but it does not perform well for irrigular areas, contrary to what some have said. The worst thing about it, though, is that shortly after I stopped using it it stopped turning, rendering it useless.I have previously had four Gilmour Metal Zinc Sled Base Pulsating Head Sprinklers (Model: 967ZDGF) that I bought at Lowes. They look great and work just fine for anywhere from a few minutes to a few hours, but they all eventually stopped turning. Thus they are useless except to water one spot. I have some sprinklers of other kinds that keep on turning, so it is not just something strange that I am doing. I have used sprinklers for many years, and the Gilmour brand is the only one that has failed me.
