Query: Sharp EL-1750V Printing Calculator

Purchased this for my 91yr old mother. When she got it she was thrilled. Her old Sharp calculator bit the dust - it was only 50 year old! It had all the features of her old one plus more. Important to her were the large keys and display. If she gets half as much service out of this one I will be thrilled!
