What could I say that hasn't been said before? There is a reason that the 12C has been in production for more than 30 years. The combination of the functions available, the placement of the keys, the RPN, the horizontal layout and those beautiful clicky buttons combines to make this a true pleasure to use. Although it is perhaps not as intuitive as menu-based financial calculators, it rewards the user who spends the time to learn how to use even a fraction of what is possible. Once you understand the layout and logic of the calculator it will become much faster to solve finance problems than with other calculators. The keystroke programming is easy to learn and can automate repetitive tasks. I highly recommend this calculator, and to anyone considering using it I recommend investing in the time to learn how to use RPN, rather than the also included algebraic input. Once you understand how RPN works, you will wonder how you ever managed without it.Read full review
