Muy buen producto

Good for school

Muy bien producto, mi hija la usa para la universidad y ha sido de gran ayuda para ella

My kid says it works great! The price wasn't too bad either. My child was able to find and use all the functions a bit easier than other scientific calculators before. The box did come in a bit beat up but all good so far.

It's good

Bardzo dobry - kupiłem dla syna studenta - zachwycony

Perfect for son’s A level exams

Great calculator compact durable has all the functions you ever need would recommend

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.

Très bon produit.
