Incentivized reviews have rated this product an average of 4.7 while reviews that were not incentivized rated this product an average of 3.7. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.
