PortPlugs Vintage Style Wooden Abacus Soroban 13 Column(10.7 in) Math Professional Abacus for Adults Kids with Guide Handbook and Reset Button, Anti-Skid Rubber Feet

Based on this analysis, the PortPlugs Vintage Style Wooden Abacus has received overwhelmingly positive reviews from a small but credible group of customers, with an average rating of 4.5 out of 5 stars. The high scores for Review Content Quality, Review Velocity, and Reviewer Credibility suggest that the reviews are genuine and helpful, which is reassuring for a product in the educational category where accuracy and effectiveness are crucial. However, the relatively lower score for Seller Reputation (78/100) indicates that the brand may not have a strong track record of customer satisfaction, which is a concern for consumers.
