編輯評論
The Casio FX991EX Classwiz Scientific Calculator has received a generally favorable reception from users, highlighting its advanced features and functionality. Many customers appreciate the value it offers, especially during promotional discounts. Users recommend it for its array of capabilities, including variable memory functions, which allow for storing Constants for easy retrieval. With many pre-programmed Constants and the ability to edit formulas post-calculation, the FX991EX simplifies complex computations, making it ideal for students and professionals alike. However, not all feedback has been glowing. Some users have expressed dissatisfaction with its size and ergonomics, preferring the compactness of earlier models like the FX260. The key design has drawn criticism for feeling cheap and producing a rattling sound, along with concerns about the readability of some labels due to the mottled surface. Furthermore, the V.P.A.M. (Visual Programmable Algebraic Method) entry method, which is touted as a principal feature, has been deemed cumbersome by some, as it requires additional clicks compared to more straightforward input methods. Despite these critiques, the FX991EX has been praised for its aesthetic appeal, quick performance compared to competitors, and its harmonious blend of modern design and functionality. To some, it stands as a worthy upgrade in technology with exciting features, such as the QR code generator, enhancing its usability beyond simple calculations. **
