These offers and everything is trash.how could you believe 10000mah powerbank for just 50 rupees or something.this site official address is from gurgaon, haryana.they never lift the call if you them and your product never gets exchanged neither refunded.i had ordered powerbank and sony headphones and got both defective ones and not even a sony headphone may be he bought it from railway station which is very small one not suitable over head and powerbank worked rarely for one minute.called him back messaged him but never replied.so dont become fools believing all these false reviews of everyone.before that check consumer complaints upon these site in online.many became fools
