Definitely needs a weight for the bottom. When windy the umbrella swings around when unbrella is unopened. Also sways in the breeze when open.. nothing to set the unbrella on a certain tilt. But overall works well to bring shade with the size of unbrella, love the LED lights underneath. Made sturdy. Easy to set up. I ordered the navy blue and looks awesome when my patio is all set up for the day.
