Beautiful, incredibly sturdy. It does pretty well with windy days, has a design that allows for movement at the place where the umbrella attaches to the arm. 
We filled our base with play sand, took 7 bags and was a tedious job, but worth it as it will provide more weight than water would. Be sure to fill the base relatively near to wherever you will be placing the stand. It will be very heavy and difficult to move once any weight is added. 
An additional fabric sac was included that could also be filled with sand for added weight. We filled this as well, very good quality products and sturdy so far. 
Easy to fold when not in use and has a Velcro strap to keep it closed and attached to the arm.
