I received my deflector on Monday and installed it Tuesday evening for a day trip on the following day. The difference was immediate and amazing 100 km/h now feels like 50 km/h without the deflector. And if I can believe my fuel consumption gauge, the deflector reduces the consumption by 1 litre/100km (about 10%), but I will not know for certain until the next fill up.

Thanks for creating such a great product.
