I have used 2-3 Micromax of same package category, I would say micromax sells advance phone at low price, in starting phone works well for some time, once your phone et older it start paining you. Micromax care centres are one of the burst support facilities in India. They have 100 of people waiting for their number and in a very suffocating environment.
Again Micromax Canvas Nitro A311 a low budget phone with high configuration but similar to other Micromax phone it has poor quality inner parts. Battery back up is low, phone heated very fast games is just hell on the phone. Don’t buy!
