My umbrellas brake all the time and those huge double canopy ones are annoying in crowded streets like NYC. There is a company that sells Senz Umbrella and I found their demonstrations on youtube. It is supposed to handle over 80 mph winds without inverting or breaking. The umbrella has an unusual kite shape that makes it aerodynamic. I have never seen anyone with them around here, but they look so convincing. Would anyone know if this Senz umbrella really worth the money or just another gimmick?
