The material feels very valuable. It is heavier material and can not be compared with the plastic tarpaulins or which are more like tentage. All pieces of furniture are including dry and remain so, even if after a downpour of water remains on the plane, not about the Waser through the fabric by. Through the vent holes always enough draft is under the tarp that is not moldy or musty. The two buckles (3 or 4 would be better) can be attached to bench and chair leg and tighten the elastic band the tarp.
The tightening is then, however, a problem. At the points where the material collapsing (which was with us on the side of the case where the elastic is the tensioner) captures the substance after just 4 months to break. In sum, I would say, this ceiling is similar to the one we had before a maximum of 3-4 years do their service before you have to be disposed of, only that this time 3 has cost so much.
Let's see what does the dealer to so far at least I could not read the other buyers that they had the same problem.
