Normal mobile users and music lovers without any second thought go for it but heavy gamers and photography lovers should not go for it. *. Heavily bloated, so many unnecessary apps some of them even can't be removed by a normal user. (Lenovo never thinks of user experience) *. I'm not a big fan of Mediatek processors but these days to cut the cost of devices companies have no choice left. If you are a heavy user might see some performance issues. *. No backlight for capacitive buttons(Home, Menu and Back) *. Average quality pictures from the Camera. *. Nonremovable battery. *. No good protection(O-ring or boundary) around the camera lens.
