Just got this recently. Probably less than 500 miles on it. It just comes up into wrong place height wise for me. At full up where it is the most quiet, the top of the shield is right at eye level and I have to either extend up to see over, or scrunch down to see through it. I bought a CalSci from another member on here. Whether that works any better remains to be seen, but I won't need both.
Here is a like to the place I got mine:
