Maybe it’s not fair to rate an identical replacement product by the failure rate of the same part it is replacing. But I have had these Hunter nozzles in my yard for years, and after a while a high percentage of them stop rotating, or worse, they don’t fully deploy and create a short-distance plume rather than a spider spray. So, I keep coming back and buying more. Like an addict. There are other rotator nozzles on the market, now, so consider some other brand.
