My son is in year 10 and I bought this for him as was recommended by his teacher.  The calculator looks nice and is easy to use.  Thank you to Calculator Direct for stocking this (I tried a few other websites and they are all out of stock) and Calculator Direct is selling this cheaper than anywhere else I have seen as well.  Prompt delivery.  Definitely recommend.

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.
