It is not as good as expeted.
Its feature is good but
Processingis not as good as other phone like asus zenfone 5
Zenfone laser
Zenfone selfi
I will recommend you to buy asus zenfone series
I have used both zenfone and k3 note also
I have experience more lagging problem in k3 note than in zenfone 5.
Zenfone is computer type mobile .it have no lagging problem .
Sound quality of k3 bote is better than zenfone 5
