Summary: Very good scientific calculator. RPN mode helps make calculations quickly without extra keystrokes. Very good and sensitive keypad and easy to read high contrast display.
Summary: It's rather annoying that when in Hex mode, entered numbers still default to decimal. Entered numbers should default to the current radix mode.
Summary: I asked for a replacement for a "32S RPN Scientific" calculator that I've owned for many years and LOVED, but unfortunately it died (and no it wasn't batteries.).
Summary: HP has done a great job with this calculator. While it's not built exactly like the classic series (HP-35, HP-65, etc.), it is still a fine calculator.
