CasioJF-100BM Standard Function Calculator,Multicolor, 4 1/4 x 6 7/8

I have had one of these Casio JF-100BM calculators for the past 10 years, and the internal charge battery finally gave out, and would only work in strong light to power the Solar cells. They do not really make these to be repairable, although you can if you are really really extra careful. For me, I snapped the case while carefully trying to take apart. I like this calculator so much, it was just easy and economical to buy a new one, and I really like this model. It does everything I want it to, very easy to use, and packs nicely in my briefcase. The size is just right - not too small, and not too large. Great calculator.

Good buy. Arrived early

Solar power backup so you may never need to open up the unit and change the "button cell" battery (that a kid could reportedly swallow), easy-to-the-touch keyboard, clear display, not expensive, and 10 digits which are good for doing taxes for all except the very filthiest rich people.Possible downside for some: No option for attaching a portable printer.

I helped my aunt get this item as her calculator is decades old and is very pocket sized. She likes this calculator and uses it since it arrived, she likes the size and the buttons. Great buy

Can't change battery. Once it drains, you might as well throw it away. The"00" key is a bad idea- pretty much useless. Keep using it instead of the "0" key. Big display and otherwise functions well.

Works great as a basic calculator to keep on my desk. Use it almost daily.

My last one "going strong" for 9 yrs now, & I needed an extra; no contemplating necessary. Great Product if it performs as old one.

You can't go wrong with Casio. We have three of these units scattered around the house since they are so reasonable priced.
