My go to Calculator for fast business financial margin calculations.
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.

.An excellent choice for me
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.

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

My aunt likes it
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

Throw-away design
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.

Best basic household calculator ever
You can’t go wrong with Casio. We have three of these units scattered around the house since they are so reasonable priced.

Además de su tamaño, me agrada que puedes programar la tasa de IVA para que al solo toque de un botón lo agregue o lo reste.
