ROATEE Scientific Editorial Review
The 991EX 552 Functions Desktop ROATEE Scientific Calculator stands out as a solid choice for those looking for a dependable scientific calculator with additional features like a writing tablet. Users appreciate its sturdy build quality and clam shell design, which sets it apart from more traditional models. The calculator's multiview 6-line display presents numbers clearly, making it particularly accessible for younger users or anyone who may struggle with smaller displays. However, the calculator does come with certain limitations. While it features a writing pad that has garnered positive feedback, many reviews express disappointment over the lack of backlighting, making it less effective in low-light conditions. Additionally, it has been noted that the device does not lay completely flat when opened, which can be a minor inconvenience during use. It's crucial for potential buyers to recognize that this model is not a graphing calculator and lacks advanced programming functionality, meaning those who require more complex features may want to explore other options. Overall, the 991EX offers good value for its price and serves well as a basic scientific calculator, complemented by its e-writing slate. While it may not fulfill all needs for power users or students needing graphing capabilities, it's a favorable option for casual use and younger students. **
