There isn't any more than that if as much holding the whole windshield on to begin with. So personally I don't think that's a real concern. It does look kind of crappy, but i do see the merits of the design. While the short shield is very dark I don't think one would want to try to see through it in the rain. So having the upper part be clear makes sense.I have seen it and I think it looks terrible with the top part on it ,,I owuld not like to be travelling at speed with 3 small bolts holding on the top of my screen ,, Might be ok around town ,but at 100mph on motorways???
