Rated 1 out of 5�by ScottThomas Bad Quality
Similar to a previous posting, I have used this calculator since college 25 years ago. I sadly replaced my college HP 12c 5 years ago and have gone through five of these little guys since that time. The quality and workmanship is terrible. Sticking keys, keys that don't register on the display, error displays....And forget about HP customer service...they were not help at all. Of course I didn't have the receipts for all five and there are no serial numbers on the units to prove that you have it in your possession. I offered to send them my five bad ones to prove a point but they would not take anything through the mail. I offered to make a copy of the back of the units, but they did not want that either...only a receipt or a serial number that does not exist will allow them to help. Stay away from these units unless you want to replace them soon! If other HP products are of similar quality, they will have a hard time staying in business.

Rated 2 out of 5�by KevinL Ditto - Poor Quality Compared to Original
I've been an HP 12C user for 30 years and my story is almost identical to the one below (Poor quality compared to original). My first 12C performed without a hitch from 1984 until I lost it in 2009. I bought a replacement that worked well until I dropped it on a sidewalk without the case. It was never the same, so I bought the Platinum Edition two years ago. That unit has had issues with sticking keys for at least a year. At first, it was the #9 key, now it's #4. I have to mash down hard to get it to register a 4 at all. If I'm not paying attention, a six-digit number with a 4 in the middle becomes a five-digit number with no 4. I'm about to take a week-long class that requires heavy calculator usey, so I'm probably going to get another 12C and just hope that I can get two years out it.

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.
