Bought this to replace a HP 33S that I had worn out, Some of the buttons had broken free of their pivots & were floating around under the faceplate. Totally happy with the new one. Glad I was able to find a direct replacement. Some of the newer HP calculators have changes that I don't really care for.

I have no need of calculators that graph or know the sine of a secant, or calculating the log of a log.
It works really well for being more accurate than a slide rule. From this buyer, it came with a pretty good instruction manual, which I respect. Great value for the money.

Mine came without batteries at all, inside the calculator or outside the package, even though it says: "Batteries 1 CR5 batteries required. (included)"
Other than that, this is a quite decent calculator. The stats functions are a bit annoying to deal with, but they work. You just have to read the manual.

Like the fact that this scientific calculator keeps the digits keyed, displayed, so you can easily see if you had typed in the wrong numbers or not. Didn't need all the functioning, but for the price, it's one of the best...

I dislike intensely the general design and the keyboard layout, especially the size and placement of the ENTER key, but the feel of the keys is very good. I like the twoline display format, but the decimal point is close to invisible, and this has caused me to make some mistakes in using the calculator.
I bought this calculator because I had owned two other HP RPN calculators previously and I wanted a new one to use in my side business. I have since bought an HP35S to use in my day job, and I am much happier with its key layout and display. The '35S hadn't come out yet when I bought the '33S; the '33S was the only scientific (as opposed to financial) RPN calculator I could find on the market at the time. If the '35S had been available at the time I wouldn't have bought the '33S. Having said that, though, I'm too frugal (cheap) to scrap this one and replace it with another '35S, because it is still working well after 10 years plus of use.

This is my second time buying it. First time, I used it for college Gen Chem I and II. This time I am using it for college Gen Physics I and II. The best calculator! I don't like the TI30Xa. If you are in between this and that, buy the HP 10s.

The decimal is really hard to see. That is really my only complaint.

Great calculator for the money. Love the two lines and the ability to recall the answer from the last calculation easily...makes advanced physics solutions much easier.

My husband has been using this calculator for several years and when his finally failed we were more than pleased to be able to replace it with the same model at a reasonable price.
