HP 15C SCIENTIFIC CALCULATOR

This new model holds up well to the HP calculator tradition. The keys feel good. Construction is good. The form factor is ideal. The increased speed is nice, too.

If you prefer RPN (and you should) the HP15C is the perfect calculator. I have been an engineer for over 30 years (still technical) and have lived in fear of my old HP15C giving out. Although it is still going strong I was delighted by the new run of...

It's great HP re-released the HP15C. My original was stolen at work in the 1990s and I've missed it ever since. The new Limited Edition version is every bit as good as the original. Perfect layout. Good tactile feedback on the keys. That old solid HP...

It's about time that HP finally is again making available a RPN calculator worth purchasing.

I could never afford this calculator when it first came out. I was only in grade school at the time. I always wanted one. Later when I started working and started college, I chose the first HP Scientific calculator I could afford, the 20S. I still have...
