I have heen using this device from 2 months now so I know what problems you will occur if you buy the device
1) the audio quality is good but not up to the mark and the speaker is located at back so it is hard to listen to songs on youtube if your phone is laid on a desk or something and the speaker is covered, a front firing speaker would have been appreciated
2) the body of this device is mostly made of plastic and it doesnt feel premium even though the back is made up of metal but as soon as u pick up your device you wil know that it is made mostly of plastic only a back panel is metal
3) the device is running android 6 ( marshmellow) which is outdated at the moment as lenovo isnt famous for rolling out updates so I dont think it will ever get the noughat update as android o is coming soon
4) battery life is really poor , I m a average user I only use instagram and youtube but this phone with full charge only makes it up to 3pm evening and that is bad considering that I m an average user
I wouldnt reccomend this device as it has too many problem but the performance is really good you will never have any problem will the device for performance but you will be annoyed by the other problems and would want to throw this device away
I will reccomend you to buy the moto g5 as it is really good device or buy xaomi redmi note 4 both are really good for only few extra thousand of rupees
