I bought this sprinkler to deal with a newly seeded lawn that I needed to water daily.  I liked the idea that this sprinkler can move through a relatively large area unattended.  I dislike this sprinkler because it "jumps" the hose regularly (even though it is laid straight, nothing in the way), it's gears on high-gear stripped after half a season and finally it's just slow to cover the area it is trying to cover - my old sprinkler (back and forth fan style) put just as much water down in less time so even though I would have had to move it a few times - at least I could water the lawn in an evening.  I haven't dumped it (yet)- but it's not worth the money...
