Pretty much the best calculator I’ve ever owned
Pros:More updated interface than the TI-84Simple to useOpen source hardwareEpsilon (the calculator’s “OS” (more like a math interpreter) is open sourceThin and lightCosts less than the TI-84 plus ceLess confusing naming scheme than TIUses a more updated chip than the TI-84 Plus CE (STM32 ARM Cortex M4 based microcontroller vs Zialog eZ80)Runs MicroPython (which is good for running custom code on the calculator, like a stoicheometry calculator for chemistry)Web-based interface on computer that allows you to update the calculator and upload python codeClean designApp-based interfaceIt doesn’t just give decimals and fractions, it gives both, and can simplify expressionsCan calculate complex numbersCons:No dark mode (Small complaint though (and it wouldn’t fit in with the white theme of the calculator)Cannot write custom apps or install custom firmware. I found this out when I was trying to add an overclocking script. I got everything set up, but a critical folder on GitHub was blocked off. This does make sense because it prevents people from writing cheating software for the calculator. Since it’s been approved for exams like the SAT (and that’s one of the main selling points), it has to store all user data in RAM, and if you could modify its code you could have a user program permanently on the calculator that could allow you to cheat on a test. They could have made it completely open source in hardware and software, but that would have made it not legal on any standardized test.Buttons are somewhat mushyLimited button layout compared to ti-84 plus ceNobody else really has this calculator so there is less available for it than is available for something more popular like the ti-84 plus ceWhite plastic is easy to scratch and markGraphing program is slow when navigating because it redraws all of the graph every time you move.Keyboard is hard to use (but that’s because I am not used to typing on a calculator and there are not very many buttons)The video shows some of the calculators features in calculator mode.

Prefer this calculator for ease of use
I’m not in the education field, I use this calculator occasionally, often for unit conversions and some analysis. I find this calculator one of the most intuitive graphical calculators I have tried, and one of the faster ones as well. It’s not the most featureful calculator, but it works well for me, and I don’t have to reference the manual a lot.Numworks has been extending this calculator’s feature set consistently from its introduction. The early models used a really light color yellow to label the second functions on the keys, but that has been corrected. The calculator seems pricey at first, but the software upgrades make it worth the money.Updating the software is very easy, you plug the calculator into a computer, point the browser at the Numworks website, log in and off you go, no need to install any vendor specific software as with so many other products out there.All in all I’m very impressed with the quality of the software.

Amazing Calculator
as a 9th grader, i believe this calculator is much better then the ti84 and is much more user-friendly.

Great software, good hardware
Pros:-Excellent software, open source. Numworks (the company that makes it) releases updates every 2 months or so, bringing new features each time.-Easy to use, feels modern and well thought-out.-Compact and very light.-Graphing is really, really, really fast. Basically instant.-Regression is very easy to use, and accurate.-The equation solver is the best I’ve ever seen in a calculator. It solves almost any equation/system of equations extremely fast, and does not stutter or lag.-It includes a Python shell that can run almost any program with basic modules. Great for beginners in coding. You can also upload scripts from the computer.-Screen is nice and clear, and the brightness is able to be adjusted.-Battery life is nice and long.Cons:-No finance application. Hopefully this will be fixed soon.-Python editing on the calculator feels slow.-Buttons can be a bit sticky.-Secondary function letters can be hard to see.-There is only 4 KB of memory available for Python scripts. This could be fixed in an update, by allowing scripts to be archived in ROM.-Scripts clear when the battery completely dies.Conclusion:A great calculator for high school, with several things that could be fixed through future updates, and few that cannot. Easy to use and program.Would recommend.

Très bien, de conception et de fabrication française !! Très bonne interface et des fonctionnalités très contemporaines et utiles pour les lycéens d’aujourd’hui. Agréable à utiliser, son coté design ajoute de la beauté, ce qui contraste avec les design typique des calculatrices. Très, très bien !!

MicroPythonが動いたり、WebDFUでブラウザからファームウェアアップデートできたりと、かなりモダンかつ良く作られている。筐体もオシャレで、無理な力を掛けない限りは壊れなさそう。また、この中で動いているOSはオープンソースで公開されており、学習しやすいレイヤに分けて構成されている。https://github.com/numworks/epsilon実用的かと言われると、まだ不足している機能(RPNとか)は残っているが、組み込みソフトウェア学習者にはかなりオススメ。そうか、自分で実装すればいいのか…
