I rarely write a review, so this is saying something for me... I agree with Rich in his 2014 review in every regard, and I WISH I would have read that review before I ordered this windshield, but alas I did not. I would re-emphasize, the install instructions were far too minimal, particularly for those of us who are bike owners, not technicians. (I searched the web and called the company also for more - there wasn't). I have been adding and taking aftermarket items on my bike(s) for decades, and this set of instructions was difficult X5. In the end, the new hardware for attachment to the bottom front end of the windscreen did not fit - at all, so I had to use stock hardware. And (as Rich said), I surmised nothing but badness if I did not attach those (nonexistent) top screws, so I drilling (very very carefully) 2 new holes, and made the 2 more anchor points for my crossbar and GPS. I believe this is now sturdy, but... as a design for stock BMW's, inferior. I am now reluctant to purchase other things in this regard. This shouldn't be that hard - the bikes are mostly all the SAME.
