Rated 2 out of 5 by Wonderful design/Poor quality The 12C is a wonderfully designed calculator for financial professionals. RPN is an efficient way to process calculations and the built-in equations functions are extremely useful. Unfortunately, my calculator's screen began to 'burn out' after about a year of use. The numbers displayed are no longer clear. Full disclosure, the calculator was heavily used over the last year #I was preparing for levels 1 and 2 of the CFA#. The unit was purchased new from Best Buy. The design is wonderful but the production execution is flawed. I will be purchasing another 12C but I hope this is not a continuous issue. July 29, 2015
Rated 5 out of 5 by The Best Bought as a gift for my son He loved it Had an older version July 4, 2014
Rated 2 out of 5 by Poor quality compared to original I have been using an HP 12C since my grad school days in the mid-1980s. I still had the original from then until just a few years ago when it was lost (or stolen?). I am now on my second replacement. The quality of materials and workmanship is definitely lower now than it was in 1985. The first replacement worked fine for 1-2 years then started yielding inexplicable and inconsistent errors in calculations. The second replacement - which I've only had for two years or so - now has a defective #1 key. The key doesn't fully spring back up when released and has to be pressed VERY HARD to get the #1 to register at all. Obviously, this makes it very difficult to achieve any sort of speed, which is one of the main advantages of RPN. I will be getting another replacement now, sadly knowing that it, too, will probably have to be replaced within a couple of years. Because of the price, it's hardly worth pursing the matter with HP, but I'm very disappointed in the quality of the current product. I downloaded an HP 12C app for use on my iPhone. It works fine, but it lacks the tactile sensation of the real thing, so the process of using it is much slower than on the real HP 12C. April 3, 2014
Rated 5 out of 5 by 12C is absolutely the BEST. Since its introduction in about the 1075's I have bought at least 12 12Cs for myself, family, and friends. I now have one by my PC (HP of course) and my reading chair. They are an important part of my life. October 18, 2013
Rated 5 out of 5 by A Tried and True Business Tool This calculator wouldn't still be around after 30 years, largely unchanged, if it wasn't a superior product. The platinum edition adds some features and enhancements that weren't available on the original gold 12-C, but the essence of an outstanding RPN calculator remain. All professional financial analysts and professionals should own one of these and learn how to use its powerful features. The 12-C is the quintessential H-P flagship device, despite all of the other wonderful devices they've made. H-P is to be commended for continuing to market it. July 16, 2012
Rated 4 out of 5 by Great Calc Great calc. I wish they included the original case and not this cheap looking one that the calculator sticks in and can't get it out if left in there for over a day. Anyone know where to get the original case design? Some keys work intermittent at times like 7 and ON. July 5, 2012
