My son assembled the umbrella with minimal assistance from me.  Some of the holes didn’t easily match up and I think a few of the screws should have been a bit longer to better secure the pole on the stand.  I called Wayfair to request a replacement screw that wasn’t sitting properly.  Having said that, I am generally pleased with umbrella though it’s been up only two days.  It’s covers a large area on my deck and looks lovely.
