Trouble free, zero maintenance for 16 years, too bad they don't make them anymore. No obstructions to slow down or create turbulence. A great performer in light winds, while alsobeing bullet proof in high winds,.Self furling about 28 MPH winds, with a large dump load control box if the grid goes down. The tapered steel pole was one of three holding up a Sinclair gas station sign, and one day my crane service got a call to remove them as the station was being torn down. They were going to be cut up and hauled off for scrap, I traded my crane wrok for them, a great deal for all concerned. I sold the other two, and still made a profit, besides getting mine for free.
