Im currently using redmi note 4 4gb black one and I think that its totally worth the money.I did a detailed study of this mobile before buying it and discussed are its pros and cons.
It is the cheapest 4gb ram mobile available in the market.it has 13 mp back and 5mp front camera which does exceptionally good as compared to other mobiles in the market. 4300mh battery distinguishes it from the other mobiles.
Im using this product for like two months now, and im completely satisfied by the performance, battery backup and its camera.I have observed that the device overheats when kept on charging but still I think its worth a shot given it s2 day long battery backup.
