    Fantastic Product

    I bought this calculator last week for my brother who is starting his GCSE's this year and I have previously owned one of the these calculators for the last 6 years and it has worked exactly the same as the first day I bought it. Would highly recommend this product to others and anyone looking for a reliable calculator for their children or for school/work.
