Great calculator, flexible and handy
I'm an electrical engineer and I've used this model as my primary calulcator for the last 30 years or so. It's a terrific model, I love the RPN and also find some of the builtin conversions useful day-to-day. Battery life is great, keyboard feels great as per HP. This model has loads of programmability even though I tend to use a computer for the fancier work these days. I wanted to purchase a second unit as a backup on ebay, and am happy I did so.
