Most Helpful Customer Reviews
I have used HP financial calculators for many years and own four. Other than the presence of RPN, there is nothing recognizable about an HP product in this calculator.
The mix of functions appealed to me because it took some of the most frequently needed functions and put it under one hood. However, from there everything else that you would expect to find in an HP financial product is simply not there.
Cheap...the unit is not up to HP standards in material quality.
The keyboard keys are not solid and have a sticking feeling of a $4 pocket calculator.
The display is small and there are too many tiny symbols and a scrolling message that is unimpressive and not necessary.
Non-intuitive...everything takes far too many keystrokes to get to the answer you are looking for. The overall logic is not consistent with any other HP financial calculator I've used. I had to re-learn everything I thought would be present in this unit...
I bought the HP20b because it can be used as a development system for the microprocessor that's inside. HP supports such hacking by making the complete details of the calculator available on it's technical web sites. See the November 2009 issue of Circuit Cellar magazine for the details. While it's an excellent calculator in the functions it offers it's lacking in the quality of the keyboard. I've own many HP calculators and this has the worst keyboard. The tactical feedback is poor, unlike all the other HP calculators I own. This forces you to look at the display when entering numbers. Otherwise you might not make correct entries. Very annoying way to use the calculator. I would rather pay a bit more and get the traditional HP good tactical feedback keyboard. Other than the keyboard the calculator is good. Display is easy to read and of sufficient size.
The included slip case is not well padded and would offer little protection when it's dropped. Manual is...
This calculator is my favorite. I just love the way it looks, compared to all the financial calculators I have used. Sleek design, HP did a wonderful job designing this device. With an also easy to use interface and intuitive form it was a breeze to incorporate into daily use without even consulting the manual.
