Nice RPN calculator for the money.  Better than the smartphone calculators.

Works well, a true RPN calculator.

Much more accurate than the RPN emulators on my iPhone.  Have to get used to the display, old-school segmented LCD screen.

I am in love with RPN but more so the stack. The stack gives a satisfying feeling of continuity when operating on large systems, and makes everything flow just right. The number solver is the best I have ever worked with. The programming language is not hard to learn if you are inclined to programming. Also the custom soft menus makes the fastest calculator.

Good calculator.  It's fast, low noise and produces results as fast as I can type.  It is a bit large, but it's so much better than my previous calculator.  I highly recommend this product.

These calculators are the greatest for a simple calculator to keep in the pocket. I have been using them for years and for the price are great. I am not easy on the care of the calculator but usually get at least a year or more out of each 1 with hard use and rough treatment. Sometimes will get 1 that the battery door likes to slide off the back so I would put a piece of tape on it and good to go. A normal person usage one of these should last for many years plus the Battery/ solar power is excellent feature.

Love this. Quicker than constantly busting out my phone calculator.

this is a great calculator lots of built in funcionality(CAS) and the document storing feature is good the font looks niceand smooth but like others have said the numerical keys are abit too small and close to.each other wise no additional complaints thus far

All I needed was a calculator that had nCr and nPr functions that wasn't upwards of $100. This calculator satisfies those requirements. It does all a basic calculator needs to do, and capable of permutations and combinations if you're in a very basic stats course (or discrete mathematics, like I was at the time of purchasing this). It was surprising to me how many calculators didn't have those 2 functions, but thankfully this calculator did and performed them correctly.

I like this calculator very much.  The buttons are a comfortable size as it the overall machine.  I like the large 12 digit display.  Use it almost daily.  To prolong its life I keep it clean and dust free in a draw.  I can strongly recommend it.

This calculator works great and is priced reasonably . I love the two lines- you can see the answer but it also keeps on the display the variables you typed in

Works good. It does what I need it to do. But the Casio fx-9860GII is a better calculator in my opinion. It has the  Natural Language Feature that I prefer to work with. For this reason I have rated this model with only 4 stars.

Super easy to use. Accurate when compared to calculations.

Performs as expected!  Good small desk calculator.

The calculator is a superb device and is best used by those who need the sophistication of an advanced calculator. Be prepared to devote the time needed to study the User Guide (included CD) to fully understand how to use the calculator.  Of course, the option of using RPN or conventional data entry is most appreciated.  My applause to the engineers at Hewlett Packard.

Nice sturdy calculator.  Can set the decimal point so no need to put it in with the number, saves time.  This calculator has great features not found in other manufactures.

Good Calculator.  I like it much better than the ones that run on batteries.  Would buy again.

The Victor 6500 many not be the most expensive calculator, but it is one of the best. The display is quite large and easy to read. The buttons have a  feel that is unlike any other calculator. They are easy to push with a slightly longer travel. The "feel" of the buttons make this calculator worth it.

After several months of using this calculator, I have to say that there are few calculators that give you more bang for the buck than this one. As many other reviewers have noted, it's very easy to use. And really, in my opinion, any calculation that takes more than about 20 keystrokes (except maybe one-var and two-var data analysis) is unwieldy for a calculator, anyway. Calculators are for tedious-by-hand but quick-and-dirty-on-the-calculator kinds of calculations. For anything more complicated, you should switch to Wolfram Programming Cloud or the Sage Cell Server (cloud versions of Mathematica and Sage). Even graphing is usually better on a computer than a calculator.

This calculator will get you through high school algebra and geometry, pre-calculus, calculus, and statistics. It's even quite good enough for physics and engineering and more advanced mathematics courses (with the above caveat).

My only slight quibble with the design is that the multiplicative inverse command is not immediately available, but only through a 2nd button push. I use multiplicative inverse so often that I would want that function pushed up as an immediate command. Otherwise, I think it's very well-designed, and far superior to the TI-30(whatever).
