Analysis Details

Never-Verified Reviewers
95 of the 4,524 reviewers have never written a verified purchase review. The Never-Verified Reviewers have rated this product an average of 3.4 while the reviewers who have written at least one verified purchase review rated this product an average of 4.3. 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.
Take-Back Reviewers
1,242 of the 4,524 reviewers have had at least one of their past reviews for another product deleted. While this is more Take-Back Reviewers than we'd expect to see, the discrepancy in ratings between the Take-Back Reviewers and reviewers who don't have any deleted reviews in their history isn't significant enough to rule out the possibility of it being due to random chance.

396 of the 4,524 total reviews for this product use substantial repetitive phrases between them. These reviewers have rated this product an average of 4.4 while reviews without substantial repetitive phrases rated this product an average of 4.3. 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.

We discovered a total of 4 deleted Reviews for this product, with an average rating of 4.5. Even though deleted reviews don't affect the average rating, the fact that action was taken to delete reviews raises some red flags about the integrity of the reviews for the product as whole.
There are a few limitations to keep in mind regarding the Deleted Reviews test:
- We don't have a magic ability to collect every single deleted review; we can only identify reviews as deleted if we collect them on one date and then notice they are no longer visible on a subsequent date.
- We have no information on reviews that were never published in the first place.
- We also don't know why these reviews were removed. It could be action from the platform, personal decision by the review author, part of an entire account closure, even some data error on our part, etc.

- 63%
- Created over 79 days
We counted 4,524 reviews for this product over the span of 803 days, an average of 5.6 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 15 or fewer reviews on any given day.
However, we see the following 79 days exceeding this threshold:In total, we found that 2,841 reviews were created on just 79 days. This is an excessively high number of reviews submitted on these high volume days.

Brand Repeaters
1,448 of the 4,524 reviewers have reviewed other products for this brand. While this is more Brand Repeaters than we'd expect to see, the discrepancy in ratings between the Brand Repeaters and non-repeaters isn't significant enough to rule out the possibility of it being due to random chance.

- 73%
- From reviewers with an overrepresented participation
We see the following 3 participation groups with a statistically significant greater concentration than what we'd expect to see:In total, we found that 3315 reviewers (or 73%) are within an overrepresented participation group. This is an excessively high number of reviewers in overrepresented participation groups.
