Yellow Mountain Imports Digit Standard Abacus 27 centimeters - Professional 17 Column Soroban Calculator (Functional and Educational Learning Tool)

The Yellow Mountain Imports Digit Standard Abacus is a well-made and durable learning tool that is suitable for both professionals and beginners. With its 17 columns and functional design, this abacus is designed to assist with calculations and provide an educational learning experience. The quality build of this abacus is highly praised by customers, with many stating that it is better than other abacuses they have purchased in the past. The weight of the abacus is also appreciated, as it provides a solid feel and should last a lifetime. However, there are some concerns about the beads of this abacus. They are described as light and slippery, making it difficult to feel a slight resistance when moving them. This can lead to the beads moving around with any movement of the base, potentially messing up calculations and causing frustration. Despite this issue, the Yellow Mountain Imports Digit Standard Abacus is a steady and easy-to-use tool, according to one customer who bought it for their daughter's abacus learning. The customer also suggests that a "clear the bead button" like those found on wooden abacuses would be a beneficial addition. Another customer notes that the abacus is suitable for children as well. However, they mention that it feels smaller and cheaper than expected, although it still gets the job done. Overall, the Yellow Mountain Imports Digit Standard Abacus offers good quality and functionality at an average price. While the light and slippery beads may cause some frustration, the abacus remains a useful tool for education and calculation purposes.
