As always with Amazon very fast delivery and professional service. When attaching I noticed why the price was so cheap, because there is the size of the film very few pull-through holes and the included cord is very thin. The first light winter storm had then covered immediately, because you simply can not zusammenzurren very firm it with the few pull-through holes. If you take other cord and still as stones to weigh it's probably ok, and not a bad price.
While other films offered are considerably more expensive, but perhaps have a better mounting system.
