Summary: I own a Casio -115 ESS Plus. Compared to the Casio calculator, this TI looks very impressive. I really like the Casio, but there are more functions on the TI, your calculations are retained even when the calculator is turned off(not so with the Casio) , and there other features which make the TI a very good choice. I do not like the buttons for division multiplication, minus, and plus on the TI calculator. They are etched on chrome, and a very hard to read.
Summary: The logic and lay out of the calculator are outstanding. Why I kept it. Although when I think about its flaws. It was a toss up. But it has flaws that stop it from being perfect. That only an experienced mathematical type person can work around. It does give wrong answers when pie is used in fractions. That is the worst and hardest thing to get around. The slide plate is flimsy. Then the chromed keys. With lighting glare, they are hard to read.
