German forum has some discussion and some great pics of this screen fitted. (go through all pages of the discussion - 6 at present).
I have not had time to translate all the discussion but it looks as though (like every other screen, some liked it more than others and different folk found different settings suited them better.
The good point seems to be it is adjustable and it appears to be a bit wider than the standard which should offer some additional protection.
Whether it is better or worse than others?????
Looks a good option though
