Micromax express 4g Q413 is a great mobile phone for 6k. It sports a 5" display which is very convinient to use.
Micromax mobiles never lag or hang.(Rarely get slow on very heavy use).
It is best option in its range .
It’s only drawback is very small battery capacity. Its has a 2000 mAh battery which gets discharged very fast.
It also doesn’t support VoLTE.
Its square edges give it a very different look from others.
Camera quality is very poor. It does not focus properly and u need to hold it steady for too long.
