I adored this sail shade when I first saw it in a catalog (and thought the price was too high), then, lo and behold, Great Offer Stock had it!
It's gorgeous, rugged, cool-looking: My only (minor) complaint is that one of the pieces of hardware was incorrect (the plastic bag had been opened, and probably returned, for this reason). A little tweaking, and we got it to work. I will echo the other comments, too: This is not a quick-install job. It took my handy boyfriend and me 2 hours, ladders, and power drills to get the job done, but it's worth it.
It's weathered super-high wind and rain, and has stayed put--also, not having an umbrella on our deck really clears out space.
