Customer ratings and reviews for HP 12C Financial Programmable Calculator

Rated 5 out of 5 by The world's best Since 1976 when I enrolled at Digital Equipment Corp. gave me a HP 12c Financial Calculator, we are in 2011 and yet I still use. It's great is damaged I would buy another. August 25, 2011
Rated 5 out of 5 by These are the best I had a 10b a few years ago and was disappointed with it. I have used various hp scientific calculators for work and school but still need to perform business math at the same time. I finally gave in and purchased one. It's great for date calculations and financing. These calculators have been around for 30 years and quite a few people still use the same model. They are built very well. July 24, 2011
Rated 5 out of 5 by HP 12C - rock solid I've had and used an HP12c calculator for over 20 years.....the same one. Built like a tank, still performs flawlessly. I'm not surprised that after all these years HP is still producing them. Mine has been a constant companion....actually been with me longer than my wife. Highly recommend this product. March 18, 2011
Rated 5 out of 5 by A Tank Picked up my 12C at a yard sale for $5! I've used it for years and love the durability and the feel of it. I'm addicted to RPN since I got my 12C great product. This is my all time favorite among dozens of calculators. February 4, 2011
Rated 5 out of 5 by Superb Quality Years ago, 1984 I purchased my "1st" HP 12C. Today, 2010 it CONTINUES to work FLAWLESSLY. In comparison, I do not believe ANYONE can make a better calc. You cannot go wrong with a 12C by HP. December 17, 2010
Rated 5 out of 5 by shocked I was shocked when, perusing HP printers via an add on my e-mail, I wandered around to look into calculators, just to see what was up etc. When I scrolled down to see if the 12C was still around after seeing all the photos of the newer, cheaper models that are out today,I was amazed to see the 12C exactly as it was in 1983 when I purchased mine. What an awesome little calculator it is. buttons, display, battery life, all perfect. In a way, it's like the shark or the cockroach, in that the evolutionary line seems to have reached a perfection of sorts. Mine still works great when I use it; and my manual, although bound with duct tape, is still as helpful as ever. December 3, 2010
