Covers a windscreen eg Renault Scenic only partially from on high. Material is "lapprig" - that is to say that when the wind half the mat to the "ears" turned up by the wind and snow and ice are thus held only in a very small part. The included suction cups, which are to prevent this are not really usable. Either they come already deformed in the delivery or deform in use. The tubular rivets (hole rim) for fixing the sucker is not stainless. Price-performance ratio fits absolutely not - therefore only 1 point.
