Screws holding spreader arms pulled loose releasing spreader arms...needed to disassemble and put arms back in place, then reinforced the halves of the hub by drilling and installing safety wire to hold hub together, hopefully for the rest of the season. It has been in use for less than three months with no high wind exposure or abnormal treatment. I am disappointed with the strength of this design, though I do love the color and appearance of the umbrella. I really wish it had been built stronger.
