Love these sprinklers! Our hard sand/rock yard finally broke my first one, so I ordered 2 more.
Unit I purchased from big box store made me order another Sprinkler. The one that I received doesn't spin as well as the first one I purchased...tried WD-40 and lossening the connection with not much difference....revoleves very slow, regardless of hose used.
Used this sprinkler for the first time last night. It is easy to push into the ground and the height can be adjusted which is very handy in a flower garden. With water turned up all the way, it watered a large area, probably 40-50' (I guess that would depend on the water pressure, and I am on a private well, so pressure may not be as high as city water pressure), but I was also able to use if for a smaller area, about 10' diameter, by decreasing the water pressure. I love that it is totally quiet and is versatile.
Excellent Product for covering a large area with a minimum of moving things around!!
So far, so good. And I learned that this telescopes!
