I really like the extra rib construction because here in the "Sunshine State" we get deluged by late spring and summer rains. Most are tropical depressions that include strong winds.  I used to have to semi-lower the umbrella to keep it from catching in the wind and inverting. Recently this happened and ruined my umbrella, reducing it to totally useless twisted and bent ribs and fabric.  Wet and unhappy, I vowed to find an alternative and found this great umbrella, and in fabulous colors too!  Super!
