it took much longer than 30 minutes to install, as stated; while I did have a problem with the initial clips, I contacted customer service for the company and they were very helpful; when you slide the panels, the rails sound cheap; it's a bit confusing sliding the panels because they don't always go back to the correct position (eg from criss-crossing the panels from side to side); we cut the panels to length but it should be mentioned that they relaxed and are now touching the ground so we need to remove the panels and re-cut again (very time consuming, if we would have been warned this would occur we would have cut shorter); it would help to have options (for purchase) to give the header a clean finished look (eg valance)
