Really amazing phone it is.
Using it from past 6 months.
I have some of the pros and cons as per my usage.
I play a lot of games and I hve experienced these things in the flagship killer oneplus two
Pros
Supports all high end games like gta asphalt and all
4gb ram
Good camera quality
Style swap covers
Fingerprint sensor works really well
Design is great
Thin
Aluminum body
Worth the price
Cons
Heats more than I expected
Slow os updates
Weight is more due to the aluminum body
