Micromax is very popular in indian market for budget phone. My father used this gadget from past 1 year and he is very satisfied with the performace of mobile.
Normally, the batttery backup is very good. He always praise this mobile because of no hanging and heating issues. Moving on, Customer support provided by micromax is really nice.
Side looks are really impressive and the overall design is really handy. So if u are plan to buy a new mobile then unite 4 is also a good choice.
