I bought this phone from Amazon at the time of its launch. They offered me great complementary deals. About product, it initially comes up with the Android kitkat version but is upgradable to lollipop.
The screen is pretty large and easy to swipe. It gives you decent experience of Android, but sometimes it gets heated while charging.
Not a hardcore gaming phone, but advised for those who have limited use of phone such as emailing, whatsapp, facebook, etc. If you compare features viz a viz price - it is worth going for. Overall a decent android phone to use.
