One ring opened and one bag tore from the second use in about 4-5bft. If you don't overfill the bags, they don't stay stable, and if you overfill them, they obviously tear... Additionally, it requires excessively much space to set up. On the positive side, it provides very good and large shade.

1st setup with wind around 5 Beaufort, we were 2 people and 3 other bathers came to help us. To set it up, 4 held the 4 poles and 1 buried the bags in the sand hoping it would hold. In the end, they gave us 2 bags with rope and we added those, and then it stayed firmly in place. The hooks on the ropes are fake and all opened. I will put stronger ones from a locksmith. Also, with extra bags, it is quite stable in strong wind. It definitely needs practice. Unfortunately, we were beginners and on a beach with wind, and we struggled.
