Hey shin, if you didnt notice we have a trusted seller for the V911 on the forum, his name is kausha.
And he sells it at Rs.3300 and its V911 V2.0, buying from him is a better bet than banggood as the box can be held by customs and you can be charged a lot, for it. If you dont want to go through that hassle in which you could be charge 50% for the parcel a it is a hobby item i suggest you buy from kausha.
Here is a link to his page:
