I brought Lenovo 6000 PLUS MOBILE last 4 months Back.
It working well.
it support Dual sim 4G LTE+ GSM,
8mp Front / 5 Mp rear CAMERA,
2GB RAM & 16 GB internal RAM.
CPU Quad core 1.2 GHZ

it s light weight and hand held mobile, it s cost is 7000 Rs
Lenovo 6000 Plus is the only mobile with all above configuration will get in this cost.
