Analysis Details
Never-Verified Reviewers
157 of the 5,922 reviewers have never written a verified purchase review. The Never-Verified Reviewers have rated this product an average of 3.5 while the reviewers who have written at least one verified purchase review rated this product an average of 4.2. 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
274 of the 5,922 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, it does not appear to have a significant impact on the overall rating.

The Single-Day reviewers have rated this product an average of 4.4 while all other reviewers rated this product an average of 4.2.

- Created over 257 days
We counted 5,922 reviews for this product over the span of 1,610 days, an average of 3.7 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 11 or fewer reviews on any given day.
However, we see the following 257 days exceeding this threshold:In total, we found that 3,598 reviews were created on just 257 days. This is an excessively high number of reviews submitted on these high volume days.
Brand Repeaters
1,607 of the 5,922 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.
Brand Loyalists
150 of the 5,922 reviewers have reviewed multiple products but half or more of their reviews are for this brand. While this is more Brand Loyalists than we'd expect to see, the discrepancy in ratings between the Brand Loyalists and non-loyalists isn't significant enough to rule out the possibility of it being due to random chance.

- Reviews have been deleted
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.
