This umbrella base worked perfectly because it's weatherproof and I put concrete cinder blocks inside of it to weigh it down however the holder for the umbrella is bigger than the stem of the umbrella and it does not tighten well enough so I had to attach rope to the umbrella and wrap it around the knobs on the umbrella base so wind doesn't pull the umbrella from its base. But I still like it and nobody's going to steal it that's for sure.
