Micromax is going quite good these days.
I have used both micromax unite 2 and micromax unite 3 .
Both devices are very nice I never faced any lagging problem
1GB ram is good for doing multi tasking.
Battery once charged to 100% lasts more than a day with average use.
Music And sound quality is ok.
Display is fine.
Rom 8gb is ok for storing data.
A good phone below 6000.
One thing I dont like in this phone is its charging time.
It takes me about 3½ hours for full charging otherwise phone is ok with good features
