HP 33s Programmable Scientific Calculator

HP 33s Programmable Scientific Calculator

A powerful, programmable scientific calculator at an attractive price. One of the few calculators allowed for use in the NCEES (National Council of Examiners for Engineering & Surveying) exams. In addition to being able to switch between Reverse Polish Notation (RPN) and algebraic modes, this calculator offers a 2-line readout, 15-digit internal precision, HP's fastest math library and numerous other features.

Excellent value and performance, 07/18/2009

Overall Rating: 5 out of 5 5 out of 5

I love this calculator's versatility! It is programmable and is a must-have if you are taking any Land Surveying or Engineering tests. Just don't leave it on the dashboard of your truck like I did my last one. :-( They don't like excessive heat.
Get one!!!

Review 2 for HP 33s Programmable Scientific Calculator

Broken after 2.5 years, 06/12/2009
By Arto
Overall Rating: 1 out of 5 1 out of 5

Time to buy a new one after just 2.5 years on a desk. The decimal point & "8" keys work intermittently. The springback device seems to have worn out - those keys jiggle when you rock it back & forth.

Not the quality I had in my rugged old "Made in the USA" HP-21 & HP-33E - they lasted >10 years. My HP-11c (sideways kind) lasted 15 years in a shop environment.

This one seemed kinda cheesy-plasticky when it was new - I guess first impressions are correct.

Good Price & Quick delivery from Wally World online, though. I think I'll get another model (HP 35s) from here again.

HP-33S better than earlier version, 02/17/2009
By cybear
Overall Rating: 4 out of 5 4 out of 5

HP finally got it and redesigned the 33S for a visible decimal point and better recognition of the digits. My old HP-33S (which died after 3 years due to a stuck keypad number) was not as reliable for battery life, numeric and decimal recognition. And of course the fact that you can lose all the programming if the batteries die or are not replaced quickly. But it is better than the HP35S which has the poor feature of STO/RCL on the same key (shift for one).

I've been a fan of HP calculators with RPN for a long time. This model continues the line. It has some very nice features and a very thorough manual.

I love HP, 11/15/2008

Overall Rating: 4 out of 5 4 out of 5

I have a couple of HP calculators and I am a big fan of RPN entry. This calculator is nice because not everyone in my family likes RPN and they can input using algebraic format too. I like to solver and programming features.

This is a great calculator. It is the best calculator for the national engineering and land surveying exams. The TI and Casio Calcs don't compare.

Defective, 09/19/2008

The zero key was much less sensitive than all of the other keys. Everything else is so good I am exchanging it for another one hoping to get one without the defect.

Love this calculator, 05/16/2008
By designerjan, Houston, TX
Overall Rating: 5 out of 5 5 out of 5

This calculator is exactly what I wanted. I use fractions quite a lot at work, and this is perfect for doing basic math in fractions, and in doing mixed fractions and decimals. The HP33s is very easy to use and has great instructions. This calculator is exactly what I need for work, and performs complex match equations remarkably well.
