    This machine is not bad for RPN logic at this low price point, so I would like to award it 3.5 stars, if possible. I only use basic TVM calculations and arithmetic and percent functions.

    Criticism: The rubber feet are strips that are convex, causing the device to rock on a flat surface when punching the unsupported outer keys. Now I have applied four self-adhering feet in the extreme corners to prevent this. I suppose the sharp edges make hand holding it more secure, and my finger stabbing the low-resistance keys is not tiring.

    I miss the bold numbers with large comma separators of my antique vintage HP 15C scientific, which was expensive, and the battery life (24 years). That one is still running, though a black substance is oozing into the LCD panel and a segment has burned out at year 25. Like most cheap commodity items, I do not expect the 20b to last that long!

    I have HP 12c which is a great calculator. Easy to use, slower than I would like but a good calculator overall.

    I needed a second calculator for my home, so I decided to give another model a try. HP 20b looked like a good second calculator for the home.

    Oh how wrong I was. The keys do not respond as fast as I need them to. Because of this, I have to double check the screen every time. Twice now, I noticed that when calculating FV on 20b my results are incorrect.

    The calculator itself feels like a cheap knock off from “black market”. Besides this is the first calculator that did not come with a case. Plus, why in the world did they put scientific calculations in there? (sin, cos, etc…) I will never have the need for it.

    Please if you are thinking about purchasing this reject of calculators, STOP!!! Do not waste your money!!! Buy 12c or 17bll+ (which is what I am getting [the old version, because from what I've red, the new one is just as bad as 20b]).

    I guess HP quality calculators is the thing of the past. Now they just make bellow average products, just like the rest of the calculator makers.

    i bought this expecting a good calculator and what i got was a big dud. the keys don’t have a good tactile feel at all, and worse yet, you have to press hard for them to work and then sometimes they don’t work. i get tired of having to keep looking at the display all the time as i’m entering numbers. the construction quality is mediocre at best – it does not have a good solid feel to it at all.

    once upon a time hewlett packard used to make the best calculators in the world – years ago i used to have an hp 25 which was superb in every way and also had the hp 10b which was a very good business calculator, but in my opinion this one is well below either one of those. to all of those who decide to buy this calculator – i hope you have better luck with it than i did.

    Purchased this as a replacement for a “retired” 19bII. My primary calc is the 12c, and this one is the back-up. Does what it is supposed to and if you are familiar with the 19bII layout, this one will have zero learning curve. Good choice at < $50.

    My 10-year-old HP 10b died. I assumed another HP would be comparable. Rude awakening. The good news: it calculates faster. The bad: the buttons and the form. The buttons give you get zero tactile verification so you have to look at the screen every entry. The form? My hands are large, but I can’t hold it comfortably. It is beveled so the small face is in your palm. As a result, it tends to be unsteady in your grasp. It has good rubber on the back, so it is OK on a desk, but it is a poor shape for hand held work.
