What's in the box Calculator, batteries, user manual, premium protective case
HP 35s Scientific calculator is rated 3.8 out of 5 by 132.
Rated 5 out of 5 by from HP Ownership I have previously owned two HP's during my entire career as an engineer and while in college. Overall averaged about 16 years for each of the calculators. Both had been awesome. I am contemplating making a framed shadowbox featuring the old calculators as a way to honor them. I could not bear to just toss the calculators even though they had failed. I was so sad when each of them finally failed but happy to find the 35s. The new one sits on my desk ready for any calculation I need. I love them.

Rated 5 out of 5 by from Effective Analysis Tool This calculator is an effective replacement for the HP-33S . It combines programming power with multiple functions and good memory allocation for effective analysis of problems without needing a computer.

Rated 2 out of 5 by from Failure as a RPN calculator Purchased to replace my 15C. Disappointed in the calculator as a RPN calculator. Appears HP tried to reach some of the algebraic users by including the ability to use it as an algebraic calculator. However, to do so they compromised key features of the RPN but making it more difficult to use functions and features that I use on a daily basis in my work. The key advantage of a RPN is the reduced number or key strokes needed for many calculations. This advantage is lost on the 35S.

Rated 2 out of 5 by from Few Choises for RPN Calculators I've got an old HP11c that still works perfectly to this day. I've gone through two HP32sii that have had keypad faults rendering them useless but I really liked its features. So I've broken down and bought the 35s. The displays is very nice. The keypad feels very cheap. Even worst than the 32sii and no where close to the feel of the 11c. The Theta symbol is easily confused for the number eight. Given the nice display, HP could have easily made the Theta symbol smaller and rounder, making reading polar number far easier. The Hex functionality seem nothing short of moronic. When the display is set for Hex mode, the user must still specify entry of a Hex number because the calculator defaults to base 10 entry. Then for Hex A-F, it uses keys labeled H-M. I guess because it was the only row with six keys in a row? It seems like all the good calculator designers have long since retired and they just threw a collage grad on the project to get the job done. I'm on the fence with this one.

Rated 1 out of 5 by from C’mon HP, Improve Quality! Keys don’t register properly, some click, others don’t. As the keys are the main factor inputting data into the machine, poor key quality means poor quality overall. C’mon HP, improve quality!

Rated 5 out of 5 by from HP 35s scientific calculator This calculator replaced my 48s that died. I never came close to using all the features, and this has all the features I need for quick calculations at my desk. I have grown up with HP and RPN way of entering numbers.

Rated 5 out of 5 by from Great calculator and RPN is a must have. Like the two line display. I do miss the comma delimiter inserted for the thousand, million, etc upon entering a large number.

Rated 1 out of 5 by from 'Tan' key non-functional when received The HP 35s calculator's 'Tan' key did not work when received. (There is a self-check technique for checking each key - I strongly suggest doing this when you get your calculator.) The short lifetime for the keyboard (zero lifetime in my case) seems to be a recurring theme in many of the reviews here. Like many others, I have been buying HP handheld calculators for decades - pretty much since they first came out. I probably have a bought about a dozen of them. The quality and lifetime clearly has been declining in the more recent models, as is my desire to replace the one I just returned. I was hoping to get a real calculator because I hate the zero tactile feedback keyboard on the WP 34s on my iPhone, but I would rather have no tactile feedback with a glass-screen iphone-calculator then a real calculator with a physical keyboard that is non-responsive.
