My dad bought this phone for him about a year back. Lenovo a6000 plus is a pretty good phone at this price bracket as it has good specs such as 2gb ram and a descent battery and a good rear camera and front camera for descent selfies. The display is also good and you get about 4-5 hours screen on time and can use about a more than half day without charging it with a descent usage.
Also it is a 4G phone and even on 4G the battery backup is pretty good and the call quality and sound is also good. It a a good package at such a price and is been updated
to android lollipop and is working good without any issues. The phone doesnt lags much but can observe a bit lag on heavy usage. The phone looks normal, not much great it is all made of plastic but had survived many falls and the speakers are also good .
My dad is being using this phone for about a year now and the device is quite good as compared to other devices and is a good value for money.
