Currently iam using this phone(Asus Zenfone 2 laser ZE550KL). I have been using this phone from the last 8 months and found many drawbacks in its performance.
At first the phone looked to be fast and brilliant but as the days move on after 3 months my phone lacked the speed and given poor performance.
Phone gets very slow and strucks every time and moreover its software wont work perfectly it shutdowns automatically and its design is very slippery that means definitely you should carry a pouch for your phone.
Finally it wont satisfies you in performance and the touch does not work well and gets stucked repeatedly. The only thing matters is its good battery life
In my opinion this phone wont meet value for your money.
