Scientific calculators are more than just tools for simple math. They’ve transformed from basic devices into pocket computers that handle complex tasks like algebra and statistics. A popular choice among students is Casio, known for its user-friendly traditional algebraic notation. This style makes it easier for learners, unlike the reverse-polish notation used by other brands like TI.
Recently, there’s been a rise in counterfeit Casio calculators, particularly the fx-991 models. The fx-991EX, released in 2015, is a favorite, but the newer fx-991CW has received criticism for changing the user interface, leading many to deem it the worst in Casio’s history. The video from [Another Roof](https://www.youtube.com/watch?v=F64lNlDgFiE) highlights these issues, showcasing how some online purchases can result in fake products.
This brings up an interesting question: Why not just use smartphones with calculator apps? While they are convenient, many prefer scientific calculators during exams for their simplicity and tactile interface which aids in muscle memory. However, the CW model’s problems have made teachers prefer the EX version. Unfortunately, this has opened doors for counterfeiters, as budget-conscious parents often look for deals on school supplies.
Fake fx-991EX calculators can cause major headaches. Users report slow performance, missing features, and even errors in calculations. These issues affect both students and educators, making it tough to find reliable devices when needed. Even Casio has acknowledged problems with the CW model, hinting at a possible return to the more popular EX interface in future releases.
This situation raises broader questions about authenticity in the age of online shopping. According to recent studies, about 70% of consumers have come across counterfeit products while shopping online. Many people may not realize that they could be buying a fake, especially with popular educational tools like calculators. It’s crucial for buyers to be vigilant, sourcing from reputable retailers to avoid disappointment.
As we look to the future, let’s hope Casio not only addresses these counterfeit concerns but also enhances the user experience with its next calculator line. A good tool can make a significant difference in learning and understanding math.
