Query: Junk.

Ray "Red Devil" hit the nail right on the head. This sprinkler stalls all the time, but for me it didn't matter what I set the flow rate at. It quits oscillating at full throttle and my water pressure is not low. I have two and they behave the same.I like the concept. It's wonderfully easy to adjust compared to the traditional oscillating sprinklers, but this product is engineered badly. One has to wonder if they ever do any design verification testing on their products. They certainly couldn't have done much on this piece of junk.
