HP 32Sii Scientific Calculator

It's difficult to find a reasonably priced high quality calculator anymore. When I saw this vendor refurbishing this model of calculator, which is no longer available from HP, I was very happy. Works like new so far after a few months of use.

I have a small collection (~20) of calculators, most of them being 80/90s era HP handhelds.I prefer older HP calculators due to RPN and superior build quality.Although not my all-time favorite calculator (that would be an HP 42s) this is my favorite EDC for banging out quick calculations to supplement/check work done on the computer (HW Engineering field).I actually bought this used to replace an HP 35s, and found it is quicker and more reliable.It also has a smaller form factor and better build quality, particularly noticeable with the keyboard.Surprisingly, it is also at least as fast as the later 35s model, its 'replacement', for most caculations.I prefer using this calculator for the following features:- Compact size (truly shirt pocketable, second only to the HP Voyager line such as HP12c and 15c).- The quality (feel and reliability) of the Pioneer series buttons (again, second only to the HP Voyager line).- Few nested menus and 2 shift keys, so most of the funtions are, at most, a shift-key away.- The screen contrast is sharp, and the characters are large and readable.- Simple but powerful RPN keystroke programming method.- Fast calculations and program execution.- Fraction handling.- Form factor and key Iayout are very good (although room for improvement, IMO)- Built-in equation editor and solver.There are, of course, also a few drawbacks:- The 1-line display. I prefer 2-line for the added context when programming and for recovering in case of lost concentration.- No built-in physical constants.- Complex numbers require 2 stack registers, and are rather limited and very clumsily implemented relative to the HP 42s.- Has limited user memory (~384 B).- Programming usability is hampered due to single-letter limited labels/variables, making it difficult to recall what the labels refer to.- IMO wasted keys with the unit conversions, could have been moved to its own menu.Overall the HP 32sii seems an excellent execution in design compromise for a mid-range pocket scientific calculator in terms of industrial design and functionality vs. usability, therefore I rate it 5 stars.

No wear was visible... seemed like a brand new calculator.Once you go RPN, you never go back. Finding a good RPN is difficult, but HP made the best

Bought my first HP-32S 12 years ago from Service Merchandise, and I never had to change the batteries once. I misplaced the case, and I just HAD to buy the updated 32S II. :) Still very well made, but the one thing missing is the nice spiral-bound manual. RPN is more logical and intuitive for programming. Just a great unit.Update 11/27/2011I lost this calculator during first orientation day at the University of Arizona, in 2005 and was gutted. I had planned on using it for years to come, and ended up replacing it with a 49G+, that I wasn't enamored with. I like RPL, but there is a big difference in size and I certainly did not like where the ENTER key was located. The build quality just seemed to be much less than that of the HP 32Sii. So I purchased a 48GX New on Ebay, and that was better, as far as build quality went, but it was a little sluggish for my tastes. The thing I missed the most was just how pocketable the 32sii was. Changing my major to computational mathematics, I even tried a TI-89 for awhile. Needless to say, that particular calculator got very little use. When I went into grad school I bought a 50g, which is a great calculator, and it got me through many an exam and assignment. But I REALLY wanted another 32sii. Unfortunately they are collectors items, and the price for a decent used one was over 150 dollars. I couldn't justify that cost for a 20 year old calculatorFortunately, for me a found a seller on here that a used 32sii in "good" condition for 70 dollars plus s/h. I took the risk and was oh so pleasantly surprised by what came in the mail this week. Not only is the calculator in perfect working condition, with no appreciable marring, but the seller shipped the next day and included a case that was not listed with the item. I need to get reacquainted with this workhorse. It fits perfectly in my hand and I appreciate the build quality and the perfect placement of the ENTER key.

I'm completely satisfied with the calculator. The picture was of the actual calculator I received. (I had assumed someone obtained a batch of used calculators from a school and was re-selling the ones that were still functional and that the picture was probably just the pick-of-the-litter.)The package included three new batteries which would have cost me a couple of bucks apiece locally.The packaging was nicely done with the calculator wrapped in bubble wrap, new batteries in a separate small ziplock bag, and all heat-sealed in a plastic bag with a label with description, item number, and bar code. All-in-all a very professional job.The package arrived in two days as promised despite being ordered during the 2015 Christmas rush and delivered on Christmas Eve.The only downside was the cost. I think my trusty original HP 32Sii cost less than $50 new. It lasted well over a decade of everyday use. Our Maine Coon cat caused it's final demise by turning over a glass of lemonade on it. I expect this one will last as long. It arrived in very good shape. It's a shame some math department minion did such a poor job of permanently scarring the back of it with a heated branding iron. Twice. On both the calculator and the slip case. I'll use my original case instead.
