12c Platinum Financial Calculator, 10-Digit LCD

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.

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!

Taking the HP12C Platinum as financial calculator is the best choice. Good handling and all functional for business calculations.

Works great, quicker than the older models, great for financial professionals, fits in pocket easily, don't need to break out the computer every time I want to do a quick calculation. Hard to believe it's still this good after 30 years!

This calculator can't be recommended. Half the time the keys don't register, and thus has unreliable performance. Fix the keys, and this machine has great potential.

Faster than the 12c. Very happy to do quick calculations for customers or CFP exam

Recommended for my finance class. Switchable from Reverse Polish Logic to Algebraic input. Performs as required. Examples provided in User Manual have errors in them but once you understand the inputs required, becomes intuitive.

I used my original 12C until the feet dropped off. Six months ago I bought one Platinum and one regular 12C from HP. The regular 12C was so bad I threw it in the trash and bought this Platinum. The number keys on the regular did not contact and register the number even though it would click; this happened about one every six numbers, a frustratingId disaster. But the Platinum is rock solid. So it must be a manufacturing difference. My Platinum says made in Philippines and the regular in China. Avoid the regular at all cost. And I like the backspace key on this Platinum.
