The YU brand product is a great product in terms of hardware aspects you can never find such deal that can beat the phone but the problem you may get is in the os it is running.
YU brand broke all the records when it was first launched in India with yureka smartphone but than it started to faint the software bugs can be solved if the company provides a better software service releases the updates regularly and all that. but in terms of it`s competitors the brand cannot stand.
Anyway the YU brand phones are always great in terms of hardware you may find some problems while using the device due to its buggy OS.
