Asus is one of the familiar brand in Indian market and zenfone 5 is another splendid device but at the moment they are not good competitors at the price range of 10k
Pros-
The 5 inch screen is quite good and is gives nice grip to hold and is comfortable to use.
The display is cool with good clarity and quality of video is really good.
The 1.6 Ghz processor give good smooth usage without any lag.
2 gb ram is pretty decent for heavy usage and for normal games.
Dual Sim support and can use easily or shift to other Sim easily.
Zen UI was a new experience and is really cool to use and pretty easy to use.
It gives 16gb internal storage and supports 64 gb external over that they give 5 gb cloud storage from asus which is pretty useful.
Call Quality is good.
Rear camera is superb that gives crystal clear images at good sunlight and is oky oky in low light.
Gorilla Glass is good and even the touch sensitivity is nice and comfortable to use.
Cons-
Built quality could have been better.
The worst part is battery is gives a 2100 battery but drains on playing heavy games and watching HD Videos and on normal usage lasts only 8 To 9 hours and dont support fast charging.
Front cam is not great and dont give quality photos.
Though the in the ear headphones sound quality is good the speakers dont give nice sound, the sound quality is bad and is not loud enough.
A very good phone for normal usage but Considering the current market and price range you can go for other phones at this same prices.
