Ishihara Test Chart Books for Color Deficiency 24 Plates

The Ishihara Test Chart Book for Color Deficiency, comprising 24 plates, has elicited a mixed reception among customers. While some users find the product to be practical, helping replace older versions in clinical settings and serving effectively as a color chart, others have raised significant concerns about the quality of the book itself. Reviews highlight several issues, particularly the physical condition of the book, with reports of rips and poor print quality, which detracts from the overall usability. Moreover, a few customers mentioned an unpleasant odor emanating from the book, likening it to cheap incense or perfume, which they found disappointing for what is intended to be a professional-grade product. Despite these criticisms, the book's format received praise for its usability, especially the black background, which enhances the visibility of the color plates. However, there are notes of caution when using it with younger children, as some may not be familiar with the shapes or objects depicted. In summary, the Ishihara Test Chart Book serves a functional purpose in color deficiency screening but falls short in terms of production quality and user experience for some customers. **
