Customer ratings and reviews for HP 35s Scientific Calculator

Rated 3 out of 5 by Product is not what I expected I asked for a replacement for a "32S RPN Scientific" calculator that I've owned for many years and LOVED, but unfortunately it died (and no it wasn't batteries.). What I got was a calulator that is far, far ahead of the 32S which is MUCH more complex and difficult to use. I suspect it cost quite a bit more than what I needed and Im NOT particularly happy with it! December 16, 2012
Rated 5 out of 5 by HP hit the nail on the head HP has done a great job with this calculator. While it's not built exactly like the classic series (HP-35, HP-65, etc.), it is still a fine calculator. I bought this to use for the FE (Fundamentals of Engineering) Exam because NCEES does not allow the 50G. Even though I'll only need it for the exam, I do not see the money I spent as wasted, as this will be a nice complement to my 50G and other HP calculators. I was a bit concerned about it when I read some of these reviews. One review said that the character for "theta" was too close to the character for "8" because it differed by only two pixels. While this is true, I do not find it annoying. Another reviewer said he was annoyed because the negative sign was not vertically centered in front of the number. This is also true, but again, it's not too bad. Someone said that "LASTX" was gone. I guess he didn't look too hard, because it's right on the enter key! Yet another complaint was that the "STO" function was on a shifted key. Come on, is it really that hard to press one more key? I think the calculator could've come with more of a "case" (mine's more of a slip cover), but times have changed, and leather cases are a thing of the past (even my 50G came with an imitation leather case). All in all, I think HP has done a good job with this calculator in that it is useful, functional, and looks like the classic series of HPs that so many engineers (including myself) have grown to love so well. P.S. The first 35s I ordered had a problem with the "5" key. It needed to be pressed slightly harder than the others to get it to register. I called HP and had a replacement in two days, no questions asked. I even got to keep the first one! December 5, 2012
Rated 4 out of 5 by Too much stuff I purchased this unit to replace my classic HP10C which I retired to protect it from damage. I've used the HP10C continuously since 1979. Certainly, the HP35S does not quite have the solid look and feel of the HP10C. But then I didn't expect that it would have the same look and feel. The reviews told me that much. The calculator has some nice features but the entire package has moved backwards because the designers succumbed to the universal current desire to provide more features. So, it's cluttered. My major gripe is that STO is now a two step function. And, LAST 'x' is gone. i used LAST 'x' all the time. So, it's sort of okay but if I could have seen another calculator with RPN. then I would have taken a look. September 19, 2012
Rated 4 out of 5 by Minor but annoying flaws I have been using HP calculators for 30 years and own 2 HP35s. Basically I like this product. This calculator offers more functions than most people will ever use. But there are some annoying flaws: * The LCD is glare type and hard to read * The "Display All"-Mode is unusable because it tries to show all digits of the mantissa thus truncating the exponent which has to be displayed by using the arrow key. * Why is STO shifted and the rarely used MODE has a own key? * Why has "h" to be added to HEX-Numbers when BASE is set to Hex? and so on. The display is a real drawback in my view. Different to other reviews I never had problems with the keys, though look and feel is not quite as hp in the 80s and 90s September 4, 2012
Rated 5 out of 5 by finally a calculator that matches the 32sII The only calculator in 20 years that matches the style and ease of use of the HP 32sII. August 25, 2012
Rated 5 out of 5 by Great This is the closest I can come to the HP45 that got me through engineering physics. I worked two summers to raise the cash for the 45 back in the day. RPN, two line display, functions beyond 1975 imagination, and batteries that last 30 months, not three hours. Living science fiction. Cool. May 10, 2012
