Customer ratings and reviews for HP 12C Platinum Financial Calculator

Rated 4 out of 5 by Great tool, cheap build I read a number of reviews and see similar comments - a great tool, but cheap build. I put it into the case a couple of times and peeled off the feet the same number of times - double-sided tape to stick 'em on? Come on. Stretched the case and now it works without tearing the thing apart. Hope the rest of it stays attached. For a tool that I'll probably use for decades, I'd hope to see it built as well as it is thought out. I've had an 11C since the early 80's until it was stolen a few years ago. Miss it almost enough to buy one off eBay, but the 33s is holding it's own for now. Still have a 48 at home too. When I made the break to get a financial calculator, there was no doubt about what to get - the 12C. I'll run an HP as long as they make 'em. Can't be beat, except by their own hand. August 10, 2011
Rated 5 out of 5 by lifetime choice I have ever own more than 5 calculators. Every certain years I was tempted to some new calculators with new features, then I had to learn it over again. And repeat. After so many years of learning and re-learning new calculators I decided to stick to one everlasting calculator and give up the new fancy complex features - Use MS-Excel instead. Actually, if your task is hard enough to require a unique feature that drive a calculator upgrade, I guess you will find MS-Office handy when this task happens. I found HP-12C is the best one meeting above strategy. I have own it for over 3 years and never looked back. It's powerful enough, fast enough, reliable enough. And I also want to point out two points that are overlooked by many: 1. HP-12c has been produced for 25+ years without major change - longer than any other financial calculator in the world. I don't need to worry about replacement. 2. HP-12c battery life is freaking long. This is very, very important. I have ever purchased the most powerful, consequently most expensive HP financial calculator (I think it's HP-18c but am unsure). HP-18c takes 3 batteries and very soon I found out why - the juice runs out after months. I have to carry backup batteries on my trip. On the other hand, my HP-12c last at least 3 times longer with one single CR2032. The faulty power-on button happens to me, sometimes. I see it a manufacturing issue not an architecture design issue. There is A REASON it's produced for so long. I see this ideal to a financial guy and I won't be surprised if Buffett owns one, too. April 12, 2011
Rated 2 out of 5 by Decline in Quality had hp12c made in usa, lasted 20 years. Platinum was made in China and JUNK. Need to replace every 2 years. Like others, the keys stick or dont register. Bring it back to US, I will pay more I teach and students are not familiar with poor quality and assume answers are correct December 12, 2010
Rated 2 out of 5 by Statistic functionality Excellent functionality but does not have basic statistical functionality like M+ and RCM (i.e. recall memory) Unless instruction manual has some pages missing! November 1, 2010
Rated 1 out of 5 by hp 12C PLATINUM - Worthless The 6, 0, and enter do not always register when pressed. Therefore, 30% of your keystrokes do not take. This leads to a lot of errors, recalculations, and a lot of wasted time. August 4, 2010
Rated 2 out of 5 by Nice Calc but sticky keys Long time user/fan of HP 11 and 12 series Calcs, but disappointed with sticky keys (not registering or double registering) on this hardware. Problems developed within first year and got worse. Now looking for a different model. July 28, 2010
