Best available
Size: Small
Math teacher here- it’s hands down the best available. AP and SAT approved. So easy to use. Needs little instructions, as opposed to the competition that requires lessons on key strokes. I love witnessing my students’ love of these calculators too and the others that went a “more classic” direction are envious for sure. It’s light, battery lasts for a very long time. Display is super clear and colorful, as well as customizable. It’s also the least expensive around! I have seen promotions through the vender under $100.

Nice performance, Features.
Size: Small
The calculator has a bright screen, seems to have fast performance, good battery life. I like that it has a battery charging indicator LED. I find using the calculator very good, very intuitive. I think the price and features are outstanding for what it offers.

Great technology
Size: Small
This is for my high school daughter. She loves it as it gives her control over all the formulae she may need in advance mathemetics.

Elegant and easy to use
Size: Small
Excellent calculator that emphasizes usability as opposed to a bloated set of hard-to-use features. It is also smaller and more elegant in appearance than other equivalent models. Best calculator by far among its competitors.

Great software, good hardware
Size: Small
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.

Pretty much the best calculator I've ever owned
Size: Small
Pros: More updated interface than the TI-84 Simple to use Open source hardware Epsilon (the calculator's "OS" (more like a math interpreter) is open source Thin and light Costs less than the TI-84 plus ce Less confusing naming scheme than TI Uses 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 code Clean design App-based interface It doesn't just give decimals and fractions, it gives both, and can simplify expressions Can calculate complex numbers Cons: 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 mushy Limited button layout compared to ti-84 plus ce Nobody else really has this calculator so there is less available for it than is available for something more popular like the ti-84 plus ce White plastic is easy to scratch and mark Graphing 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.

Great calculator that will keep getting better.
Size: Small
This calculator is really good and a good price. The only reason I'm giving it 4 stars instead of 5 is because I think that is missing two features that would greatly improve the functionality. It is missing Engineering Notation and a Programmer Mode. With these features it would be a 5 start product for sure. I was also pleasantly surprised that the entire project is open source. Everything is available on GitHub including the STL files for the house, buttons and cover. This is great since anyone that doesn't like that it comes in all white, has the option to 3D print replacement parts. I was also pleasantly surprised with the company's customer service. I emailed them with a couple of questions and suggestions and received a response within 12 hours. The good thing here was that Léo, not only answered my question, he also responded to my suggestions and asked for clarification on one of them. This tells me that this company is not just interested in selling a product, but also trying to work with its customers to make the best product. Lastly, the addition of a Python app to run Python scripts is a very welcome addition to a graphing calculator. Unfortunately the only way to input Python code is either through the calculator, which isn't great, or by modifying the source code and pushing it as an update. While this is limiting, I'm sure that the process will get better in future updates. I do recommend this calculator to anyone that is looking for a good graphing calculator. I'm not sure if it is currently approved by any of the testing boards yet, but if you aren't worried about testing approval, than this is a great option. Update: I have found that, as another reviewer wrote, the factorial function does not work on software version 1.1.0. If you need factorial functionality now, I would recommend writing a Python script to do it. This sort of thing is exactly why I love that Python is on this calculator. While Python obviously isn't on here in order to workaround software bugs, it is nice to have an ability to write a script to do something that the main programming can't.

“NumWorks Graphing Calculator: Modern, Simple, and Student-Friendly”
Size: Small
The NumWorks Graphing Calculator is a breath of fresh air compared to bulky, outdated models. Its sleek design, color screen, and intuitive app-style interface make it easy to learn and fun to use. Built-in Python programming is a great bonus for students interested in coding. The rechargeable battery and lightweight build add to its portability. The only downsides are its slightly limited features compared to high-end CAS calculators and the occasional firmware restrictions for exam compliance. Still, for most students, this is a stylish, user-friendly, and forward-thinking option.
