HP 35s Scientific calculator is rated 3.8 out of 5 by 128.
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.

Rated 5 out of 5 by from Feels like home- almost After over 28 years with an HP32s, I finally had to replace my trusty calculator. (Which, by the way, should show the reliability and sturdiness of HP hardware.) And the 35s is just like my 32- almost. Some functions have moved on the keyboard, which is playing hob with "muscle memory" keyboard entries. (Example: I keep hitting the "5" key instead of the "8" key for "Hour-minute-second" conversion.) Irritating, but I can retrain my fingers. The keys feel firmer, with a more positive reaction. I really like this machine, and appreciate that RPN is not dead!

Rated 4 out of 5 by from This is an excellent calculator. hp41/42 better This is a good calculator because it preserves the superior RPN format, but it has gone backwards from the hp41/42 in terms of quality and usability. For example, take the square root of -1 on an HP42, and you get the correct imaginary answer. If you do the same thing on the HP35s, it will give you the error "SQRT(NEG)". The HP35 will only let you find the square root of -1 after you jump through several hoops! You need to first enter -1i0. Then you must raise it to the 1/2 power. You can't simply hit the square root key because that will give you the message "Invalid Data".I appreciate the fact that the price is much lower than the HP41/42, but it is a shame that this calculator technology has gone backwards while all other technology is moving forwards! Just the same, I am thankful that HP still makes a RPN scientific calculator.

Rated 5 out of 5 by from Need small version I have used HP RPN calculators for 40 years and love them. I have published code for them in 170 countries for specific engineering applications. I have been waiting for 4 decades for a small version of a RPN calculator that will fit in my shirt pocket... yea, less programming function, etc... no problem... just need a smallish version to have with me all the time... never saw it... still hoping.

Rated 5 out of 5 by from Love RPN I've been using HP RPN calculators for well over 20 years. In my opinion, any serious science or engineering student will be very well served by this device. This is the machine of choice in today's market.
