It is affordable and cost-effective device and the only problem that I face using this phone is it lags during playing Pubg and sometimes while using YouTube and other browsers. It is highly compatible and easy to handle as it's small in size. The main advantage is that you can play Pubg in this and as overall it a good device and other markable problem with MI is that you need to set up an MI account and should remember the password when you change Sim. It have a long durable battery and high quality camera compared to other devices available at this price.
