... This checkbook calculator not only tracks your balance, but provides the date and time as well. Can follow three different accounts with this product. Didn't receive five stars because one time when I opened it I was greeted by a "blackened screen". It still worked, but was difficult to view with the blackened background. Thought I was going to have to send it back, but the next time I used it it was fine. ...

... I used to be a bookkeeper, so a good, FAST, efficiently laid out keyboard is important to me. Though I no longer do that work, I still would never change from this calculator and am happy it's still available as mine finally lost its marbles and won't stop printing once it starts. (Probably it could be repaired, but these days, that's more expensive than getting a new one so...) Having the "total" key where it is -- by your thumb-- and having the single zero key a bar instead of a small key is WAY smart. You can really move on this keyboard. ...

... I bought this desktop model for the home, after buying and using the Construction Master Pro Trig hand held calculator. The desktop model makes a great companion to the Pro Trig, which I use in the field for pipe fitting and rigging applications. Both of these products were some of the best purchases I have made, as they are very versatile and offer the most funtions that I use on a day to day basis. Before now, I have either been forced to use more than one calculating device, or keep a list of the frequently used mathmatical formulas on hand to complete my work. Now I am able to work with more speed and accuracy. The set up features are an asset, as I am able to program most of the functions to meet my specific needs. Again great product. It offers more bang for the buck than any other calculating device I have tried. I am a true believer in Calculated Industry products. ...

... 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!
