The pins holding the fancy truss inside are breaking. The truss system seems very sturdy, but the pins that connect at the mid-point are very tiny. There is a lot of tension where the rods join, and the pins just can't handle it. I've also found the way the fabric is sewn to the plastic pins,the thread has broken. I haven't even been out in very heavy winds. I do not recommend this umbrella. I'm going to try and get my money back.
