Casio calculater is so hard & tough that it doesnot broke, I purchase the calculater before 2 years back & now its working very fine.
As I m student calculator is slipped through my hands so many times , 4-5 calculater is broken by me, but this calculater is best which I want i.e which doesnot broke even after falling.
Casio also give warrenty of 3 years , its amazing. Its price is also affordable only ?350.
If u purchase a chinesse calculater it cost ?110 & work only for 5-6 months & have no warrenty, but this is made in philippines by Casio computer co.ltd.
After some time digits from buttons start disappearing, & also color fade of calci.
So persons who have too much work to do on calculater must have a casio calci for fast working.
