Very sturdy and looks good. But, the part that holds the umbrella is loose and requires a wedge to stop it spinning (I used a plastic knife). Also the screw on the bottom RUSTS and in a BIG way. To solve the rust issue I put an old plastic cutting board under it. We use it with the modifications mentioned.

Nice umbrella stand

This stand is sturdy enough for my 9 ft umbrella. I only used water to fill it so it can be moved if necessary. The umbrella is taken down if it gets too windy as it would be damaged. This would not be the fault of the stand, just the nature of living near the coast.
