I needed to replace my last triangular shade sail after about 2 years due to weather extremes. I thought this one was correct dimensions, but as you can see it sags a bit  no matter how I adjust I cannot get it taut. 
Nice perk was that the hardware was included but I still think I will need rope to be able to get it just right.
Color was as expected. Provides adequate shade. Very wrinkled out of package, but it’s starting to smooth out now that it’s up.
