Not only because it covers in addition to the windscreen and the side windows, but even in high winds, in this case the hurricane Xavier holds.
For me it has not left any, as described in a previous review, scratches or similar tracks.
It has been described by some that cover very light and thin Am working with which I agree and also say that protects well against the icing of the windows and is so far not yet frozen.
Conclusion:
In value for money a good and recommendable product.
