Customer ratings and reviews for HP 35s Scientific Calculator

Rated 5 out of 5 by this is it for RPN I bought several of these in case they stop making them or at least calculators like these. The 35s has a classic feel to it, and more features than I'll ever need. Two lines of stack display is nice to have compared to classic HP. The zipper clamshell is a nicer case to have; these came with a sleeve type case from which you must fully remove the unit to use. Battery life just OK. Top edge of the screen (some tiny icons there) can be hard to see without good light at just the right angle. But I don't think there's a better calculator, and for RPN I think it's the only game in town (aside from the 33S which has a casio look to it, and a couple of expensive HP graphing calculators).

Rated 4 out of 5 by The Best Right Now You can read the many other reviews to learn about the shortcomings in the design and implementation of this product. Even with all of them, I'm very happy to have my new HP 35s. It brings back the feeling of HP's "golden years" of RPN calculator products. When HP reintroduces the HP 15c and HP 42s, I will happily throw my 35s into a box in the closet and buy each of those. But until then, this is the best next thing. To put it simply, this is the only decent scientific programmable calculator I could find that is currently manufactured. August 10, 2011
Rated 4 out of 5 by Best Effort Yet to bring back the classics This is HP's best effort yet of combing classic HP calculator design and build quality. It's been 30 years since we've been able to purchase the type of calculators that made HP the most desired programmable scientific calculators from any manufacturer. You should not be disappointed if you ever owned an HP 11c, 15c or even a 41c. I commend HP on this effort even though there are deficiencies in the feature selection; notably missing is a polar/rectangular conversion and some programming peculiarities . The overall package does shine on the key design and placement. The display is not as clear as I would like, but then again my eyes are getting older :o) This is one to own and buy an extra to keep locked away when HP decides to stop manufacturing it. Highly recommended for licensing exams and for engineering students. Congratulations HP and please keep returning to the classic designs. Now if only the 41c's would be brought back with compatible programming, expandable interface and more rich features and menus. The 42s was a good attempt but nothing hold up to the classic and easy to use design the old 41c's brought generations of engineers. I thank my lucky stars that repair services still exist for the classic HP's! August 5, 2011
Rated 5 out of 5 by Awesome, just awesome Bought this to take the Fundamentals of Engineering exam (FE) and I bought it about a month before the test to get used to the RPN and I love it. When you get used to it, it's so fast. The manual is very helpfu. The solver, is just amazing. My only complaint is that you can't have more than one variable of the same letter (w/ a different subscript) in a formula. For example: you can't have an f1 and f2 in the same formula. Other than that, I love the solver because it solves any variable. July 21, 2011
Rated 5 out of 5 by This Machine is a Winner. The big Enter key, classic looks, 30 kb for programs, and fairly cheap price make this a winner. For anyone taking the FE or PE tests, this is the machine that will give you an edge. With GTO line and indirect variable addressing, you can write just about any kind of program that can automate many of the test question calculations. The closest thing to criticism is the poor rectangular to polar conversion, which forces you to waste memory with your own routine, and you must hit Enter after XEQ LBL X### to launch a program. Addition of more unit conversions would be a useful added feature. I've bought 5 of these machines, and will continue to buy a couple every year. Hopefully this model won't be discontinued as time goes on, but if it ever is, I want a good stock of them. I don't even want to think about paying aftermarket eBay prices, like what's happened to the HP15C. The only thing that will surpass this machine for me is the introduction of the HP15C+.

Rated 4 out of 5 by nice RPN calculator in the classic HP style HP has done a good job of delivering a calculator with good functionality and decent build quality at a reasonable price. I share some of the same quibbles as others with regards to glare from the display, poor battery life, the handling of some features such as polar to rectangular coordinates conversion, etc. But all in all HP did a nice job. If I hadn't been using an HP 32Sii for the last 15 years I would think it was fantastic, but alas HP set the bar high for themselves and they have not really exceeded my expectations for them so I cannot give it five stars. I do recommend this product, and I like many others I would love the opportunity to buy a new HP15C type calculator as well. I like the smaller, more horizontal form factor. A true "pocket" calculator. July 14, 2011
