a57

I want to buy a dual SIM Android phone within Rs 5000. I have Micromax Ninja 3 A57 in mind. Is it a good choice? Has anyone of you personally used this phone? How does it perform? I am especially concerned about battery life, interface lag, call clarity and longevity. Also, what do you think...

I need to buy a phone this week and a57 really caught my eye. So, should I go and get it? Have any of you used it? Please share your opinions
