The Casio FX991EX Classwiz Scientific Calculator has received a range of reactions from customers, highlighting both its strengths and weaknesses. Many users appreciate the calculator’s advanced features, such as the ability to store multiple values in variable memory and the inclusion of numerous pre-programmed Constants, which enhance usability and streamline calculations. The clear display that shows both the entered formula and the result is also a notable feature that some users find attractive for better understanding their calculations. However, there are several critiques aimed at its design and ergonomics. A common complaint is that while the calculator offers modern functionality, it lacks the portability of older models, with some users feeling that it is too large for convenient carriage. Additionally, the key design has received unfavorable feedback; users describe the keys as feeling like "chiclets" and making an undesirable rattling noise. The visibility of alternative key labels has also been criticized due to a mottled surface texture that obscures readability, particularly in low lighting conditions. Lastly, the slip-on cover has drawn negative remarks for being loose and unreliable. Despite these criticisms, many users express satisfaction with the calculator's performance and features, suggesting that it fulfills its purpose effectively, particularly for students and professionals who require a reliable scientific tool. **
