The limited instructions showed an L bracket that was slightly different from what was included in the package, which made it a little confusing, but I made it work.  Also, one of the brackets is not as secure, as it doesn't "catch" the way the other ones do.  I don't have the patience to take them down, return them, and wait for more that may give me the same problem, so I'm going to use them and hope for the best.

Pros: Very functional, good quality fabric and shade.
Cons: Poor instructions, inconsistent packaging, and low quality fixtures.
