I bought this device from flipkart, got delivered within time.
Initially, It was very good but as time passed it started to trouble.
Two main problems were in the battery and sound.
Having only upto 2100 MAH battery giving backup of less than half day.
You need to carry your charger all the time and finding a charging socket.
Secondly sound output was very low, hard to hear even the incoming call ringtone let alone the music and all.
This was main reason to replace the Asus with Lenovo K5 Note.
