This is a nice phone with some issue and lags.
I have been using this one from last 2 months.
Pros;
Price 10000 is great
RAM and storage is good
16 MP camera is good but didnt work in low light
Fingerprint sensor lags sometimes
Sound quality is great
Screen resolution is full hd and clear
Metal body and durable
Features are good like galaxy series
Quick charge is cool feature with 4000 Mah battery
Cons:
Phone heat up quicky while playing games
Sometimes after the installation of the Official Miui 8 update phone gets hung several times with only working power button. Touch doesn't work, it might require manual update by service centre.
Its a dual sim phone but if you put a microSD carx then only one sim can fit.
If any of the part damaged or broken like( Screen, sim tray, battery, ect) then it can cost you more than the phone value. For example the screen cost is 8000, the motherboard cost around 12000 and so on.
Mi is a budget phone but they charge you from serving. The total cost comes around 25000 bucks in which you can buy 2 redmi 3.
This is my personal experience do comment or like if it helpful or need any more info about any phone.
Thanks & enjoy
