Quality:5/10Suitability:3/10Performance:9/10Added 3 stars for it functions like an original casio. 2 stars for its affordable price. Lessened 2 stars for legitimacy of the product, as it was advertised 100% authentic - it is not. Removed a star for the packaging of the product: it was creased on the sides like it was squished. Overall, I cannot recommend this product for those looking for an authentic one.

This calculator is an improvement over the previous version, loved by many fellow high school students. This revamped version includes Casio's easy-to-use conversion & scientific functions; reliable battery & solar operation; smart-looking styling; and the most crucial fraction buttons.In terms of features, this has to most bang-for-your-buck for any student. It will continue to be my top choice. And even midst the boredom that is Math Class, you shall witness your classmates lust over this amazing calculator.
