Best calculator. Review on Casio MJ 120T

I am using this calculator from the past two years.I am doing chartered accountancy course and time factor is very crucial in our examinations. We have to do our calculations very fastly. This calculator is very useful for speedy calculations. It's keys are designed in such a way so as to perform calculations very fastly . I bought it for 350 RS for a discount and two years warranty is also given . it's durability is also so good. Previously I used to use 100rs calculators but they used to break or open up in two pieces. But this particular calculator is very good. The answer is also very accurate and m+ and m-functions are working very well. We can correct past 100 steps very easily. It is very easy to use. The bettery life is also very good for this product . the print on the keys is also very clear even after 1-2 years also
