Reviews around margin (5.00 of 5)
Casio MH-10M Business Calculator

The Casion MH-10M is the next best thing to the greatest margin calculator ever, the discontinued Texas Instrument BA-20 - but it does not have a normal functioning % button (it's a tax rate % button), otherwise, it would have been absolutely perfect.

Awesome calculator, and % works as it should, despite the other reviews
