I have been using this calculator for over 4 years till now it runs amazing.
When I was in first year I had buy this calculator and now I am graduate with the same calculator just imagine I had been using for over 4 year as it is completely in working condition I had changed only battery twice or thrice.
ALTHOUGH THIS BRAND PROVIDE GOOD QUALITY PRODUCT BUT THERE ARE ALWAYS SOME DEMERITS AND I AM GOING TO MENTION IT BELOW.
1- THE digits printed on button of calculator disappers after few month .
2-Body colour comes out gradually.
3-Finishing and look of product hide its original appearance as it get old.
