Poor construction

This wind guard fell apart on first use. The connector brackets don't adequately grip the glass. They seem to be angled incorrectly so that much of the contact is between the metal and the glass, and not enough of the rubber-tipped screw heads connect with the glass. Rickety and insecure. Fortunately, Amazon accepted the return with full refund. I bought another brand on Amazon and am quite pleased with it.
