The Casio FX-991EX ClassWiz Scientific Calculator has garnered a mixed reception among users, highlighting a blend of appreciation for its advanced features and some discomfort with its design and ergonomics. Many customers express satisfaction with the calculator's value, particularly praising its advanced engineering capabilities and the range of functions it provides. Users have noted its ease of use and the capacity for variable memories, allowing them to store and recall important values conveniently. The inclusion of pre-programmed Constants is also a hit, often described as a beneficial feature for both students and professionals. Additionally, the ability to edit formulas after obtaining results, along with the entertaining QR code generator, has received positive attention, indicating that users find value in its functionality. On the downside, some customers have experienced dissatisfaction with the calculator's size and tactile experience. Several reviews indicate that the FX-991EX may feel too large for portability, particularly when compared to older models like the fx-260. Users have critiqued the keys for their chiclet design and noise, which some found unappealing. A notable complaint revolves around the readability of the alternate key labels due to the mottled surface texture, which can make it challenging to use in various lighting conditions. Furthermore, the loose-fitting slide-on cover has also been observed as a point of discontent, suggesting a potential flaw in the design. In summary, while the Casio FX-991EX ClassWiz offers impressive features and functionality, some users may need to adjust to its design quirks. **
