The Sun Shade is contstructed quite sturdily, with the seams and corner hardware properly reinforced. You need to measure carefully, and allow for enough extra room to properly stretch the shade when it is intalled. The included installation hardware, while fairly complete, could have benefitted from an "S" hook is each bag. The hardware is also of poorer quality. I have used it, and it seems fine, but at the end of the season I may purchase some new stainless steel turnbuckles and other items at my local Home Depot. I have already priced out what I want, and for less than $15 additional dollars, you can get much higher quality hardware it you wish to. Having said that, the savings I got by purchasing this item on this website more than offset any additional hardware costs I choose to have. I can recommend this item, as it has made a tremendous difference on my sunsplashed deck.
