Customer ratings and reviews for HP 12C Platinum Financial Calculator

Rated 5 out of 5 by Best choice Taking the HP12C Platinum as financial calculator is the best choice. Good handling and all functional for business calculations. December 19, 2009
Rated 4 out of 5 by Extremely good ... but I am a very long term user of this type of HP calculator - and I would have no other. The improvements to the Platinum version make it a worthwhile purchase. The increased speed was certainly noticeable. However, as other people have noted, it is prone to some keys not reacting to being pressed - and it can sometimes take a two or more key presses. The ON/OFF key on the one I have is particularly prone to this - and it can take three or four presses to wake the calculator up. But once awake, it is excellent! May 29, 2009
Rated 4 out of 5 by good for classes I bought this calculator on clearance. It was about ten dollars more than the 10b. It does so much more. I find it able to do all my finance class problem. May 3, 2009
Rated 2 out of 5 by Good performance but poorly made As a calculator, it does an outstanding performance. Much faster than the older Hp12C. I love the form factor and the RPN data entry which is the way to go. However, I can't give more than 2 stars for two reasons. First the build quality is really poor. After a couple of month the 0 key broke for no apparent reason. More often than not, I have to press twice for key entries. Considering the overall build quality, the warranty is way too short for this expensive product. Now I'm stuck with a defective product that I wouldn't recommend to my student or my colleagues at my office. March 15, 2009
Rated 5 out of 5 by Outstanding I love this caclulator. I am a MBA student and this thing is great. It would be nice to have some probability functions but with its programmability, you can just program in the keystrokes and add permutations and combinations. This is an upgrade to the standard 12c with the ability to operate in algebraic entry or the HP's RPN entry format. The RPN entry takes a bit to get used to but once learned, you will not go back to the old style. January 18, 2009
Rated 4 out of 5 by Getting the platinum I am really anxious awaiting my new platinum, I find it very usefull and reliable, maybe not as fast performing a task as one would like, but it is a calculator and for the price, it is an awsome tool to have if one is in sales, as I am. January 16, 2009
