Spot on.

All though the description of the calculator's condition was as stated "Mint", was entirely true. You couldn't ask for a better price. I was extremely disappointed in the packaging. Simple bubble wrap envelope, to protect a "Mint condition" calculator, is not sufficient. All that said beautiful product and short arrival time is a plus.Read full review

Unit WAS in original clam shell packaging with manual still shrink wrapped.

I absolutely love it. The heft and "key feel" are unavailable on calculators in the current market.

simple and good enough

Quite simple and easy to use. Good for everyday use. It would be better if it possesses RPN input selection.

Best general purpose scientific calculator I ever owned.

I have owned one of these calculators for many years and consider it the best I have ever owned and it still works. An excellent general purpose scientific calculator includes some of the most common metric conversion units and 10 memories. It enclose in a very solid, durable case.Read full review

Great Vintage Calc!!!

Why can't they make calculators like this one anymore? Simple. Powerful. Programmable. And batteries last a looooong time.
