Recently I have bought Redmi 4A and its glass cover from mi store.
I must say that it is a very good site with a first delivery. I got the delivery of both the orders In just 5 days.
And the best part is I got total 3 glass covers. That mean in the price of rs 125 I got 3 covers instead of one. Which is very rear in now a days.
Their customer service is also very good. There is customer care number in this app and they inform their customers about orders through message and email. The price of the products are also responsible.
Overall it is a very nice app.
