編輯評論
The FX-991EX Classwiz Advanced Engineering Scientific Calculator has garnered a mixed but generally positive reception from customers. Many users appreciate its advanced features and capabilities, highlighting its extensive function set, ease of use, and the ability to save values and modify formulas, which significantly enhances functionality during calculations. The built-in QR code generator also adds a fun and practical aspect for users who want to share or visualize their calculations easily. However, not all feedback is entirely favorable. Some users have expressed dissatisfaction with the size of the calculator, finding it too large compared to previous models. The button design has been criticized, with comments about a rattling sound when keys are pressed, as well as issues with the visibility of the alternate key labels due to the mottled surface texture. The Variable Parametric Algebraic Method (V.P.A.M.) entry method, while a selling point for some, has been labeled cumbersome by others who prefer a more straightforward input method for everyday calculations. Despite these criticisms, many customers still regard the FX-991EX as an excellent choice for a scientific calculator, particularly for those who value advanced features and functionality, while a few still prefer older or simpler models for daily use. Overall, it serves well as a powerful tool for engineering and scientific tasks, with deliverables that elevate mathematical solutions. **
