This product from Micromax "Micromax Canvas Spark 3" is a mobile phone well worthy of buying at this very low price range.
No one can provide a smart phone with all the essential features needed at this price.
Battery backup is little weak. But it is Ok. Can’t expect too much and everything perfect at this range.
Sound quality is good. Camera quality is not bad.
It is a very good and suitable mobile phone for the beginners and low users.
