The vents are helpful with the gusts of wind. Used at the beach, flipped a few times from wind but didn't break. Yes, uv rays make my forehead pink when i stand outside for 15+ mid-morning and early afternoon.

This umbrella rusts like a * the moment it hits the beach. It is also very bulky with the material. While great for sun protection, this umbrella is fragile junk.

The button to push it open isn't working. To close, you push the button again, but only the umbrella part closes. Keeps opening concave instead and hard to have it keep the umbrella shape.

All that money down the drain. Amazon no longer is a place you make a purchase and feel secure about the purchase without having seen and tested the quality of the product.
