Very good coverage for front and side windows including the mirror. Reliably protects ice and saves before so a lot of work during the morning preparing the vehicle in winter. The size is just right for my car (Opel Astra). In normal conditions the cover holds well on the vehicle, with strong wind, the area of the side windows and mirrors can slip covers times, since only magnets assume the attachment, a full fly the cover is not possible jedeoch, since parts of the tarpaulin in the side doors pinched and it is held as reliable (even in high winds).
