Ekomi Review Ideal for A level work
Ekomi Review When my old calculator of 15 years finally died a death, I needed something that would be able to do what my old one did. This is a great calculator that does everything I need it to (and more). Very easy to use and the screen is nice and clear. My only gripe is it does feel a bit plasticky and flimsy compared to my old one but I suppose it doesn’t really matter.
Ekomi Review Quick and easy. Can't ask for more!
