I have a dart windscreen that is about the same height but way smaller overall, and it blocks wind reasonably well up to my neck or chin depending on how I sit while riding on the freeway. I would think it's a bit better with the added wind deflection for your arms. Might not notice any wind except on your head.
There are quite a few posts about this already, check them out. The most common complaint I’ve heard is about the headlight seal being poor quality and allowing air through the opening. The rest has been mostly positive.
