| Product | Return Mentions | Est. Monthly Loss (assuming 1,000 units/month) | Top Reasons (Top 2) |
|---|---|---|---|
| B07G142F9Z | 30 / 249 (12.05%) | $4,987 | Heat function not working 6/30 (20%); Too rough/painful/aggressive 5/30 (16.7%) |

Note: Actual return rate is typically higher than review mention rate (many users return without leaving reviews); the above is a conservative lower bound. The reason breakdown uses return mentions with a stated reason as its denominator, which differs from the return-mention count on the left (one mention may carry several reasons). Estimated monthly loss uses the unrounded return ratio.
