Don’t waste your money on these umbrella stands. I purchased 2 and I had kept them in the boxes until my patio and front courtyard were completed. I unboxed them and to my dismay the screws in the post would not attach to the base. They were stripped. Of course the time to return them has past and there is no way to fix the problem. Money down the drain. 
I gave them 1 star just because they are heavy which you need in AZ because of monsoon season
