Casio Inc. JF-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.

Nice unit. Simple, larger keys and display. My 2nd one and would purchase again. Reasonably priced.

Good size, buttons are very soft and big enough, good quality

Nice color, works just like the old one. Recommend.

I was looking for an Cost Sell and margin calculator for my desk. This calculator is close to perfect. Easy to use buttons, vaities decimal places, solar. Just one issue is the kick stand and no flip screen. The kick is basically pointless. (See pics) I have had to place it on post-it notes so I can see the screen on my desk. Over all it is a great $9 calculator, my fault for being a short cheap skate.

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.

Very accurate, nice size, solid build

My wife needed one, to replace the old one .It works that's what she needed.
