I have been using this phone for quite a bit now.this are my pros and cons according to my usage and findings.
Pros-
Qualcomm MSM8956 Snapdragon 650 which is quite efficient and a big hit on Redmi note 3
microSD extention up to 256 GB
Huge 4850 mAh battery
All Required Sensors like Fingerprint, accelerometer, gyro, proximity, compass are present
Cons-
huge 6.4 1080p screen
uncomfortable grip
Lower results of camera comparing to same price bracket other phones,
