I had an older version of this calculator. It lasted 20 years before some of the keys stopped working. I got another. You can switch between calculator and 10-key functions and between floating decimal or not and between no decimal places, 2 decimal places or more. Just like a 10-key but portable and solar powered. I never changed the battery in my previous model!

The same as a big bulky adding machine .. It is light weight portable and solar powered. LOVE it! Looking a long time for something like this! Highly recommend to everyone that is used to an adding machine and can't go back to a calculator.

no quiet what i was looking for. but will do well for my needs

Bought for office desk, size perfect, easy function

I have used this calculator before in my previous job and I love it. It mirrors all the 10-key calculator functions except it's portable (no electrical chord) and I can take it with me to meetings. The price was cheaper than Amazon's and it ships fast to Hawaii.

item is good for math problem

Absolutely enjoy the larger keys! Used one at work for 11-1/2 yrs, retired, and could not stand the small hand held calculators. Worth the price! Solar powered with a battery backup. Recommend*****

It does everything i wanted, even keep a running total. only small minus is there is no backlight to use in low light.

I've had the same calculator for 15 years. No batteries needed. Flat, easy to take home from office.
