The Beese umbrella is very well-built and sturdy, covers a large area, and has a vent on top to help with air flow and wind deflection. The angle of the umbrella can be adjusted and the base pole can be rotated easily while the umbrella is open, using a foot lever. It comes with a cover. You definitely need the weighted base, sold separately. Make sure to read the directions on how to open the umbrella as it requires two hands and it’s not intuitive but once you know how to do it, it is easy to maneuver. When opened, it provides shade to over half of my patio furniture set. I’m very happy with this purchase and expect to get a lot of use out of the umbrella!￼￼
