Customer ratings and reviews for HP 35s Scientific Calculator

Rated 5 out of 5 by Awesone calculator I purchased this calculator off the web in November and got a really good price on it. This calculator does everything i expected it to do and i really do love it. My office gave me a hp33s calculator to work with, which i love also. But when i spotted the hp35s calculator, it was a must that i had to have that calculator. It does everything that the 33s does but even more. Dont get me wrong, i still love my hp33s which my office gave me to use, but i figured i had to have my own scientific calculator for backup, so i got the hp35s. Keep up the excellent work hp. Thanks for a cool calculator. April 27, 2009
Rated 4 out of 5 by Wanted book This HP 35s is a fine programmable calculator but how can I learn to use it? With great difficulty. It comes with a VERY skimpy instruction book (a flyer) barely 24 pages or so and is double spaced! HP had no trouble using small print single spaced for the warranty info in the back, but the booklet was almost a joke. I don't have easy access to the web or a home computer (to use the included CD instructions), so I took off two stars for "features" because I think a thorough and comprehensive book is absolutely a must, and is missing here. Now I have to go to the library and find it on-line and do what I can in the library's time limit. This is why I gave 4 stars in the overall rating as well. I gave performance 4 because I don't think it has alphanumeric entry like my old 41CX. It only takes in single letters at a time, not words. I know the on-line instructions is the way of the world now, and other calcs like TI are doing the same thing, but that is lame. They could have used small or very small print and gotten quite a lot in a book, and I would have been much happier. Also, it is incorrect that it comes with a hard case. It comes with a soft case that is stiff, but flexible. The 35s itself is a very impressive machine and it's the best looking calculator I've ever seen. It's a very capable scientific calc, and overall I'm very happy with it. Now let me get off cause I have other things to do at this library computer. April 8, 2009
Rated 4 out of 5 by Solid Nice and solid. I use it as a back-up. My primary hand calculator is, believe it or not, the original HP41 from the early 80's. After more than 25 years, it is STILL going strong!!! March 11, 2009
Rated 4 out of 5 by A good old HP Having used the 28S and 50G, I suppose this a a bit of a downgrade. However, it's perfect for taking with when not wanting to drag the bigger brother around! It's able to store the programs I would require out-of-office. A few points: 1) STO/RCL: the 28S had a top STO and shifted RCL. As one is likely to recall a variable more often than store it, this works better. But perhaps exchanging RCL for a less used top-key function like MODE would be better. 2) More labelling space would be available for programs if we could use 1000 to 9999. It would then also be beneficial to increase user memory to say 128K. 3) On user memory: be careful on how you use indirect registers. Use only the lowest number necessary as memory gets assigned to all from 0 to n-1 at 37 bytes each. (You can use up almost all the memory when using no. 800). This is another reason for HP to increase the memory as one cannot realistically use a lot of indirect registers with large programs. Hence performance gets only four stars. 4) In my other HP's I found it useful to convert between any like units, e.g. mile to cm in a single convertion. Also some other features (e.g. square root of a negative no.) would have been expected. All in all I really like the HP35S and think it's a great compact powerful scientific calculator together with the return of the robust design older HP calculators are known for. February 16, 2009
Rated 4 out of 5 by Thank you HP for the walk down memory lane. I will not repeat what the previous 17 reviewers have said about the functional issues with this calculator, in my opinion the most important thing we have learned from HP making this calculator is that there are still people who want a quality, well-made calculator. This one, more than just a little reminiscent of the original HP-35 that took me through college so many years ago, is a dream compared to most modern-day calculators. Since cutting my teeth on my first HP-35 in the 70's I have never been able to adjust to a cheap calculator with an "equal" sign. Please take note HP, give us another HP41 or maybe even a new HP11C. Build it and we will come. February 13, 2009
Rated 2 out of 5 by rectangular polar function the rectangular to polar function is awkward to use in non program mode. January 10, 2009
