We bought two of these. As shipped, these umbrellas are unsafe and unusable. You literally can’t even open these umbrellas (even in no wind) without them falling over. Designed by someone without even a basic understanding of a cantilever or physics. It barely remains standing in a closed position!!! Unless you have a way to bolt these to the ground, it is a MAJOR safety hazard. I can’t believe these are allowed to be sold on the site.
