I am using this device for more than a month and I am fully satisfied with this product. At a price of 16999 rupees you get a fully equipped smartphone. It comes with a 6 GB ram and has a 4000 Mah lithium ion battery which ensures smooth operation at a very low power cutdown. It also has a 20 Mp front camera which takes high definition pictures. It is also equipped with a octa core Snapdragon processor with 2 GHz capacity. It is one of the best smartphones in the market. Xiaomi has done a great job in this model.
