Must have for all engineering students

I don't think any engineering student in India needs an introduction to this device! I used the FX-100 and FX-991 during my engineering days and they were used so much that I was afraid I'd wear them out by sheer usage! The best feature of 991MS has to be its ease of use. Even if you're using scientific calculators for the first time ever, you'll figure out how to use them in no time. The 991MS provides practically all formulas/operations that you could possibly need (strictly talking about engineering or scientific operations). The simple but rugged calculator just keeps on working without any issues whatsoever. Haven't had the chance to use it much after engineering and I don't think this would be the best product for financial/consulting based industries but a very useful product nevertheless.

Very Efficient solar powered calculator

Since Casio is a trusted brand I didn't mind paying little extra for a two way powered calculator and I am sure it will last a lifetime . I recommend this over battery powered since there is little chance of leakage and also one can save on expensive batteries . Solar panel works efficiently even from inside the house.
