    Calculator works fine but if you are buying it for a level maths just a word of warning, drop it asap or if that isn’t an option then start revision months in advance. ITS SO HARD!!

    A. · 30 July 2025

    I have yet to explore all the functions of this calculator but it's far superior to any calculator I ever had. Perfect for mathematics at foundation year in university. Portable size and great value for money. I didn't have a chance to replace the battery yet, so I can't speak about battery life. Easily the best choice I made in calculators though. Thank you.
