    Big step up from the HP 33S

    When my 41 started getting flaky, I picked up a 33S on clearance at Walmart. I was pleased to find it approved for FE and PE exams, and so is the 35S. I saw a review somewhere else regarding the displays. The 35S is definitely clearer, because the pixels are spread out -- the decimal point is easier to find, etc. The keys on the 35S feel much better than on the 33S, the Enter key is back where it belongs, and the rows are straight instead of the weird chevron of the 33S -- What were they thinking? Still checking it out, the 35S has a cool way to quickly program a repetitive calculation. I am looking forward to transferring my 41 programs to the 35S.

    Would be perfect except for Keyboard

    Hi, I am a RPN calculator user for 10 years and just can't convince myself to return to conventional algebraic calculators. When I saw the HP 35s, I was convince by its classic design and because it was not a graphic calculator. I just love this calculator and I haven't nothing to say about its functionnalities, it just perfect for me. I'm a mechanical engineer and use it each day. However I had it for two years now and my Enter key is broken (it stands loose in its cavity and it doesn't punch each time I try, see pictures). Previously I had an HP 48gII that did the same thing, it begin by the Enter key followed by the number keys and after a time it is not praticle to work with. With this 48gII this defect appeared just after the end of the warranty, I wrote to HP and they changed it anyway (Excellent work). The 48gII that they sent me broke within a year (see pictures, less good design). And now my HP35s begin to have the same problem. Don't mislead me I am not hard on material. I'm a consulting engineer and my calculators always stays on my desk and don't follow me on the field. Also read, and you'll find other critics talking about those key problems. So I would not recommend this product it will just get you addict to the RPN, but the quality is not there anymore. Hope they will correct this problem a day and come back to the quality that was associated with there calculators.

    My Favorite Tool By Far

    I am a College Student who grew up with a dad who has been a loyal hp fan ever since his first calculator, The 41CX. My dad is an Electrical Engineer and he always helped me with my math. after a long time, I too have decided to follow the path to become an Electrical Engineer. When my dad found out he decided buy me my own hp calculator for College. Ever since the first time I got my hands on the hp 35s, I have not been able to put it down. Homework began to be fun due to my interest in learning to use it better, and have really grown in my confidence as a young mathematician. *The hp 35s is based around the "RPN" entry system rather than the "Algebraic" mode used by most other calculators (that aren't hp's). This entry system takes a little while to get used to, if your not familiar with it. - it took me around half a semester (3 months) to get comfortable with it- Great calculator, super powerful, awesome feel, beautiful to look at, all around it is my favorite tool for engineering by far! I seem to learn something new about it everyday. If you have previously owned an RPN hp calculator, consider this your back up. Great purchase.Thanks hp ;)

    HP Calculators New verses Old

    Have attached a image with an example of some different HP calculators (RPN) which I have used over the years and a brief summary below. Attached image from left to right HP 35s - Lasted about 10 months before a key failed. This calculator have never been out in the field. Brought this to replace the previous 35s. HP 35s - Lasted about 12 months before the keys failed. This Calculator have never been out in the field. Brought this to replace the 48Gii. HP 48 Gii - Lasted about 8 months before the keys failed. This calculator has never been out in the field. I brought this to replace my 32Sii and at the time thought it would be a worth while investment. (Big $$ mistake) HP 32sii - Lasted about 10 Years before the calculator eventually failed. All keys work up until then. This calculator spent 60% of its time out in the field in most conditions. Was also run over by a vehicle once and still worked. I brought this to replace my previous 32s. HP 32s - Lasted about 8 Years before the calculator eventually failed. All keys work up until then. This calculator spent 80% of its time out in the field in most conditions including extreme. (sorry no image attached as it's not on me at the moment.) As my last 35s has now just lost functionality with one of its keys today, I find myself at a crossroads now with HP calculators after 25 years plus.

    A step in the right direction

    I'm honestly (pleasantly) surprised a "real" calculator like this is still available in 2017. It's not perfect (the entire way base operations work is horrible, program checksums are bugged and don't work, program labels limited to single letters) but it's still a modern programmable RPN scientific calculator you can buy brand new. The industrial design and button feel is perfect, the screen is good but could be sharper (bravo for two lines), the equation writer/solver and fraction operations work well. It's great that this thing exists as a successor to the 32S series but it feels like a stepping stone to a product that may never exist: a successor to the 41C*/42S series. A modern 42S successor in this style case would probably be the greatest calculator ever made. I don't know why the business market gets extravagant things like classic and updated versions of the 12C and the 17bII+ but the area where HP has the most heritage, scientific calculators, has one decent mid range device. Why not keep the 11C or 15C in production the way the 12C is, or create "platinum" versions of them with more power and functionality? Why not make a high end version of this calculator along the lines of the 42S, with the dot matrix display from the 17bII+? I really appreciate the 35S but it feels like HP could do so much more than they are, scientific/engineering users made HP what it is but financial users get the best toys. I mean you could at least release a plus version with the bugs fixed and some UI changes (let me reiterate, base operations are awful!). The 35S is good for what it is but it would be a shame if this was the very last HP RPN scientific calculator.
