Its been more than one year that I have bought Asus Zenfone 2 and it has not shown any defects till now . it is still working as I first bought it except some small issues .I wont say that it has an awesome sound quality but its good instead. It is very easy to use and if you find it hard to use than there an easy to use function in this phone .The plus point in this phone is its RAM which is 4 gb and its Intel processer. Its Camera is good , both front and rear and its 5.5 screen really gives you a good experience while watching movies and playing games .Its also has a feature of getting 60% charged in 40 minutes .The only thing I dont like about it is its battery backup, otherwise it is a very reliable plus a durable phone .Its style is great , specially its curved body and according to its features and durability plus its style the price is very promising .It is a must buy phone ??
