I am really happy with the operation of this product.  I have used it for about a week now, and the product works easily, and does a good job of giving some shade.  The only complaint I have is that the sun does pass through the small holes in the fabric.  In some ways this is a nice feature, because it allows you to see through the umbrella, but it does not provide the same sun protection that a more opaque umbrella would.

In high winds, it has worked quite well, and seems sturdy, and up to the task of staying opened with at least moderate winds.  Also, the umbrella is huge.  Much larger than I expected, and easily covers my entire 6 person table.

All said, I believe this to be a great looking product, that I would purchase again.
