Thank you! Seems to be genuine indeed. Tried authenticity checks and it looks genuine. I was hesistant at first because there are many fake 991ex ones being sold on the internet. But internals on this calculator look genuine and solar panel works like it should. You can change contrast of the screen too. Also- unrelated but this is the first package ever that was delivered to my door. Pretty nice.

    Awesome calculator

    I upgraded to this calculator from a 115 es, and the only really difference that i cam tell is the screen. And the screen is easily worth the cost of the calculator. I'm an engineering student so I walk around with it every day and it is pretty durable. The screen makes the calculator so much more easy to use. I highly recommend this calculator.

  • Great Calculator!

    Excellent calculator, good design, lot of capabilities, the mathematical natural textbook expressions are nice, the spreadsheet is limited (it erased when the power go off) but very simple to use.

  • The best money can buy

    The absolute must-have calculator for Engineering students and professionals. Quickly solves any equation, integral, sum. Also a big plus is the ability to work in base 16 and convert rapidly between bases. The display is clear and crisp and the keys feel great.

  • One giant leap for calculator users

    This looks similar to the fx-991ES which I have used for a while but is so much better. The pixel size is smaller, so the screen is easier to read. The algebra functions look more like algebra. And it is so much faster. Trying an integration such as ((x^2-1)/(x^3+1))^0.5 from 0 to 1 on both machines together, shows the difference in speed. It solves polynomial equations up to quartics. I still have to find put what else it will do.

  • Best benefit/cost relation in a modern calculator!

    Awesome calculator! The spreadsheet is kind of useless, because any data will be erased on power off. But this is a great calculator! As a programmer my main use is on base conversion and operations. Also I strongly recomend this seller!!!
