Here's mine, F6B specific adjustable 11" - 19". It works great for me at 6' high, 11" good for around town up to 60mph, then flip it to 19" and everything is pefectly quiet again. I wanted to buy Ergomot power windshield but decided on Baggershield (at least for now!) because I think the dark tinted one just looks awesome on my black F (and Ergomot does not come tinted yet, I asked). Not to mention several hundred dollars difference. I was also amazed how simple was to install it even for someone like me who missed shop class in school. Installing Ergomot windshield scares me, and I don't have all the tools required either. But who knows, maybe in the future if it comes tinted... I do miss my power windshield on my BMW K1200LT (was black, of course).
I hope this helps.
