Casio is the manufacturer of this calculator. The company is known for developing the first scientific calculator. For over 100 years, they have manufactured high-quality calculators for students, engineers, and professionals. You can't go wrong with a Casio calculator, and the FL-CP400 L is a graphing calculator that's worth buying.

Casio designed this product for visual and dynamic learners. It's unlike other calculators that show only dark lines on the graph. This calculator offers you the advantage of seeing fully color-coded graphs after entering the function into the graphing system. Because of this, it's a great choice for students who need a visual aid when representing their graphs.


The Casio FL-CP400 L is a great tool to have. For instance, it comes with rechargeable batteries that last for up to a month of use. This places it a step above competing devices whose power begins to fail within a manner of days. Get this graphing calculator if you need something that's durable enough to last for a longer period of time.

We like the stylus that comes with the product. It allows the user to easily maneuver around the calculator’s operating system. Users are able to navigate with their fingers if the stylus is lost. This is a good feature because it gives the user the ability to interact with the calculator and learn more about it through practical use.

One advantage that this calculator offers is its 3D plots. Unlike other devices, this calculator gives users the ability to move and rotate their 3D graphs to their liking. 3D graphs are useful because they show your mathematical computations in a clear and easy to see format. This makes it ideal for engineers who need to demonstrate specific graphs for their projects.

But, there are a few complaints associated with this product. Consumers across the board complained about the slow calculating speed. After a few weeks of usage, the calculator becomes cluttered with a lot of data. This slows down the speed, making it harder for users to utilize the calculator for what it's worth. Avoid this calculator if you need something that's fast and responsive to your commands.

While this calculator is accepted in most schools, some standardized exams prohibit its use. Exams such as the SAT and ACT see this model as a tablet which goes against its policy. Make sure you check the requirements of your exam before buying a calculator.

Overall, we believe that the Casio Graphing Calculator is useful for beginners. While it's large screen is considered too much for some, it provides the user value through its large library of apps. By using this calculator, you'll notice an improvement in your college exam scores and general math skills.
