One of the worst purchases. Very poor quality. After 6 months in the island sun from May to October, it tore and became a rag with 6 Beaufort winds... Not worth it. It wasn't cheap either.

The ropes for tying are worthless, I had to re-sew the support rings because the old fabric tore at that specific point.

Do not throw your money away. After 1 month of use, it burned from the sun and it develops holes where it is stretched even a little. UNACCEPTABLE

It was installed on a pergola with shading needs of 11-12 sq.m. as an "emergency solution" for the rest of the summer.
See the last photo for an assessment of the shading percentage. For its price and the above purpose, it is worth buying.
It is not waterproof of course, and it gives the impression of being "single-use", but only time will tell.
I will return with more after strong winds, scorching sun, and generally further use.
Edit: With surgical precision, after one year a hole opened and it needs replacement, as shown in the video. My impression that it seemed single-use was confirmed.

Very nice and provides great shade. I had to change the rope as it was cut in to four short pieces. Get yachting rope so it's more secure.

It was too small for the area as the sheet doesn't fit squarely when tied tightly. It gaps on every side by about 50 CMS or more and doesn't give the cover we wanted.

Beautiful, durable, and high-quality. After one winter and one summer, there is no sign of wear and it covers the entire back balcony, hanging continuously since the first day I got it.
