Hello Guys, newbie here, so excuse me if Im posting this on a wrong place.

I'll be in India for a business trip, and just found out there is a website called indiamart and they got many sellers who sell Antminer S9.

Is there a way to understand if they are fake?

This is the link for it, could some of you please help me?
