Calculator is an important need in our life, It is used in our college as well as after
college life (office life), but some people are confused before buying any product because they are not aware about which is the good calculator. For these people my review will be helpful.
I was using Casio ms991 calculator, which is good product of Casio, there are lots of function available in it, and it is easy to operable, handle, small with good looks. Its service is also good. I used my calculator for continuously 4 years, and currently my one friend is using it. There was no any problem occurred rather than battery got over, but these calculator batteries are available in many stores, so no problem while using it. One user guide is given with it so if you are not able to operate any key then it is easy to understand by reading the user manual.
So friends don’t worry about this product use it freely.
