Get the windshield from 3S dealership. Do not buy from market . You will never get a genuine item as there are loads of copies available.
I bought one from market, it was the top most quality available and the guy claimed was genuine suzuki. All the labels , everything was same like in a genuine suzuki, but after 6 months it had bubbles popping up in glass. It was around 4500 i guess.
The price difference is not much. Rest is your choice.
