This events are meaningless they are giving only gift to their relatives . My 10 freinds bought asus zenphone 3 but even no one get 1 zenpower bank or 2,000rs cashback . And obviously this is because of asus dare of mi5 and other models become sucess upon them . So for consumer i can say you dont buy zp3 if wanna buy for cashback or gifts this all of marketing funda. Nothing new . Even asus dont know how to respect customers by reality events. I participated in all events from 7 year a littlebit i didnt get 1$ . So pplsdont waste time in it do something good work better than asus.
