Lenovo k3 note is a nice phone from lenovo.screen is very good big screen with ips display allow you to watch movie and play game with better experience.ram is also good it came with 2 gb of ram and 16 gb of internal memory.it allow to expand your memory via micro sd card or you can also extend your memory with connection hard disk via otg yeah this phone supports otg.
Price is quite achievable that you can afford it.
Taking about its design it is nice and slim.
Offcourse it is not over weighted. It is light in the matter of weight.
My friend got one from flipkart last year and the phone is running quite well.
