Everything about this umbrella is 5 Star except for its use of aluminum components in the center shaft assembly. Also, that you cannot get replacement parts. If the parts most susceptible to damage in high wind were steel we would not have had ours break when a strong wind blew ours over. We filled the base with water and it is very heavy, but not heavy enough to keep it from tipping over. We have now strapped it to the deck. We will see if the umbrella will tolerate some moderate winds. The surface area is so large even minor breezes move it around.
