I got this umbrella because I wanted its 11ft. large cover size. However, and I’m guessing it’s due to the size and very (!) shallow tiers, when even a little windy this umbrella wobbles a lot and I’m hoping the shaft doesn’t bend or break. The diameter of the shaft should be at least an inch wider and of a stronger metal. The one I took down measured 9 ft, had much more distinctive tiers and NEVER moved no matter how strong the winds - I’ve got it on standby.
