Customer ratings and reviews for HP 12C Platinum Financial Calculator

Rated 1 out of 5 by Disappointed I love the HP 12c and I still have an older one I use all the time. However, I purchased a 25th Anniversary Edition HP 12c Platinum in 2007 and it no longer works. The on/off button is hard to use and the #7 key doesn't work at all. February 18, 2012
Rated 2 out of 5 by I'm Really Mad! Just so HP knows, my days go back to saying "hi" to Mr. Hewlett at Sunnyvale in the early 1980's, where I bought my first 41C, and my first 12C. If you heard/felt the click of each key, it was a GUARANTEE that the entry of the integer/operation had been performed. Not so with the new 12C Platinum (Serial CNA 94201205). Purchased recently from a nearby "Office Max," four operation keys and the "7" key registered intermittently. I bought the new 12C because the calculator case accepted my business card, which made for an ideal gift. I received both case and calculator back from the client. I'll stick to my 20-year-old 12C.

Rated 3 out of 5 by Good Calculator, Poor Build First, I am a HP calculator fan and have always owned and used HP calculators. I purchased my first, a 48G, in 1990 while in high school and used it nearly every day studying Math and Mechanical Engineering (BS & MS) then early in my career. This 48G was and continues to be rock solid after all these years of being slung and tossed around in a bag and generally not being handled with care! Loving RPN, I purchased my first 12C anniversary in November 2004, a replacement 12C Platinum in 2006 and now my third (another replacement) 12C platinum in December 2011. While the calculator layout & functions are great, the build quality on the 12C is horrible; keys are not responsive and fail within a couple of years, case is clumsily built, and pads on back side of calculator fall off after sliding in and out of case only a few times! Please HP return back to your golden standards... I want to love the 12C like my 48G. After all, in this new digital age, if I'm going to spend $75+ for your product (and I clearly will) it should last! The 3rd party 12C platinum emulator I use on my Iphone costs a mere fraction of the actual 12 device and I can carry it everywhere with me.. but when I'm in the boardroom I want my 12C there and for it to work! Again please bring quality build back to your products then I can continue to be a faithful customer and endorser. December 25, 2011
Rated 5 out of 5 by Very Nice Works great, quicker than the older models, great for financial professionals, fits in pocket easily, don't need to break out the computer every time I want to do a quick calculation. Hard to believe it's still this good after 30 years! September 26, 2011
Rated 2 out of 5 by HP12C I bought the first one in 1978 and it lasted 30 years of very heavy use. I guess that was just too good a product for HP. Replaced it with the Platinum version less than two years ago and it is already giving problems. September 2, 2011
Rated 5 out of 5 by Switched from HP 17B II+ - Easy I have been using an HP 17B II, but had to switch for the CFA exam. The system is intuitive and easy to use. Not quite as well organized and simple as the 17, but works well. August 25, 2011
