Rated 1 out of 5�by MortgageGenius Cheap and Flimsy
The first one lasted from 1979 to 2010 and was used for hours daily before it died. It also used a watch type battery that lasted forever. Since 2011 I've had two of these s which were used very little yet had many issues. Very sad to see such a great calculator with great programming made so shoddy.

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.
