Hi today I am going to review about new Asus Zenfone 3s Max ZC521 .It’s a great phone in the market now. Price is very effortable , picture quality is awesome with HD video recording , surrounding dolbi digital sound quality makes this phone extra powerful. The battery backup of this phone is the main highlighted features. Once you charged forget for 2 days. Don’t worry if you wish to buy a phone under your budget , just go for it.
