I am using it from 12 month and it is ok.
Advantage
Stock ROM.
Battery life is Awesome.
Back camera is Very good.
Front camera is good.
Performance is Very good.
Update gets with in 2 months frequently.
Disadvantage
Fingerprint some times not work, but it can be fixed via update.
Everything is very good, I suggest you to buy if your budget is low and love asus brand, else choose another.
Thanks you.
