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.

The calculator was bought as a gift for my son's 15th birthday.  He wanted this particular model and is absolutely thrilled with it.  I think it will see him through his GCSE and his A levels with loads of functions and a really clear screen.
