semi-satisfied!

the product (awning sunscreen tarps garden, balcony, terrace, size 3x4 meters square gray water resistant), we have since 3.2012 in use.
It donated good shade and there is weitgehends waterproof. When it rains, the water rapidly accumulates in it and the sail hangs menacingly through.
We tried the sail more to tension so as to act against the problem, but then tore a seam.
The gray color is even already a little faded.

Conclusion: "can always hang" for it is only conditionally Suited, but to remove it again have it's just too big. In future we will try again with even greater disparities.
