Just three months ago I bought lenovo vibe k5 note online and I am using this phone continuously.
I did not get any problem in my phone but its battery backup is not so good as I wish. the battery backup provided by lenovo vibe k5 note is generally three hours when I operating internet . it is a lightweight phone and come with huge amount of ram there fore it run smoothly without any hanging problem.
any normal user can purchase it because it not too costly. this phone has a capability to use pendrives using OTG support system
