CATIGA Scientific Editorial Review
**** The CATIGA SS-991EX, referred to as the catigaEX, marks a commendable entry into the solar-powered scientific calculator market, drawing significant comparisons to its predecessor, the Casio fx-991EX. Customers have praised its speed and efficiency, highlighting that it performs tasks such as definite integrals exceptionally quickly—often at least five times faster than competing models from Sharp and Texas Instruments. Users appreciate the familiar layout and functionality reminiscent of the Casio's popular models, which makes it easy to transition between calculators. Despite a few design alterations, including a different color scheme and button layout, the catigaEX retains a user-friendly interface. Its capabilities are comprehensive, covering a broad range of scientific calculations, although some noted the absence of a GCD and LCM calculator—a minor drawback mitigated by the available prime factorization feature. While the calculator generally offers a swift performance, customers have expressed some frustration at the memory function erasing recent calculations upon switching modes or powering off, similar to the Casio predecessors. The button quality elicited mixed reactions; while several users found the ergonomics satisfactory, some criticized the buttons for having a loose feel, leading to a perception of lower build quality. Despite these critiques, the catigaEX is sharply positioned as a robust alternative to the Casio CW and even as a backup to the Casio EX, given its accurate calculations and essential features. It is recommended for anyone needing a solid solar-powered scientific calculator without the expenses associated with graphing capabilities. **
