Nice phone. When I bought it in 2014 december, it was the best phone for price and specification. But if you compare with the recent phones available in market, it is slightly costlier and some features missing.
In this 2 years, I didn’t faced any service issue. Every coin has two sides. If I have to say cons, then low sound volume and low image resolution in artificial lights. Beyond this, I am very much happy with my Asus ZenFone 5.
