Expert Reviews


What reviewers liked

It’s just about the cheapest calculator you can buy. Great for younger students who are not going to treat it too well, anyway. Nice Button Spacing: Because there aren’t many buttons, they’re really nicely spaced apart and it feels like you have plenty of space for typing.

What reviewers didn't like

When it comes to specializing in financial, geometric, or calculus subjects, this one just won’t make the cut unfortunately. Many online reviews have complained that it broke before long. Keep this in mind when making your purchase.
