I bought Asus Zenfone 5 around 6 months earlier, at that time I loved that mobile because of following reasons.
zenUI is attrective
Gorila glass protection
2gb ram
Intel processor
But as I used this mobile I faced follwing problems.
Poor battery performance( I had to charge twice a day)
Heating issue
Cemara performance is not that good
Till now there are many mobile like lenovo k3note, asus zenfone2 laser, hawai honor4x etc. Which are far better than asus zenfone5.
So honestly I wont recommand this mobile.
I hope u will find this review helpful.
