This wasn't the prettiest shade sail by any stretch of the imagination although the turquoise color is still exceptional at the end of the season. For the size and how it can be manipulated, it is an overpriced import from China.  It will be interesting to see how long it lasts.  However, it is perfect for rain.  Water comes through which is fine, because it means the material will not rip or tear like canvas.  This replaced the top of an outdoor  gazebo from a large retailer that was ripped to shreds during a summer storm.  The shade sail has weathered severe storms well.  It is not difficult to hang and provided the needed shade.  I am giving it a 4-star because I do not know how it will hold up over time.
