Casio Fx-991Es Plus 2 Scientific Calculator With 417 Functions And Display, Natural

Product as per casio standards. No suprise.

Exactly as expected with fast delivery

Good

Perfect working order and cheaper than what is in the markets

It is the best price i could find

Shipping packet was okay but the original product packet was opened when it was delivered. Made in Thailand was written on the packet but made in CHINA was written on the product

I bought it for ~40 dirhams (10USD) which is crazy cheap for a calculator that has this many features.

Same model same Specification

Si estás buscando una calculadora científica completa y fiable, esta es la mejor opción del mercado. Tiene tapa protectora, ideal para llevarla sin preocuparte por golpes o arañazos. Además, al ser Casio, viene con la garantía de calidad de una marca de confianza. Lo que más me ha gustado es su función de notación natural: las operaciones y fracciones se ven igual que en los libros, lo que facilita muchísimo el trabajo y evita errores al interpretar resultados. Es rápida, precisa y muy intuitiva. En resumen, una calculadora inmejorable para estudiantes de secundaria, bachillerato e incluso universidad. ¡Un acierto total!

Bardzo dobry - kupiłem dla syna studenta - zachwycony

Excellent

Five stars, since it is a decent, and affordable calculator for highschoolers. Personally, I was looking for something more, but this got pretty much the essentials; - binary/octal/decimal/hexadecimal conversions - imaginary numbers - summation - decent display utilising a matrix dot display. I am a bit disappointed with how it does seem clunky to use at times, and the interface is rather inconsistent. (eg. ×10ⁿ being one unit / seperate) Furthermore, other modes feel... limited.
