Analysis Details

Fail Suspicious Reviewers

Take-Back Reviewers


7,586 of the 27,198 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.

Single-Day Reviewers


141 of the 27,198 reviewers have written multiple reviews but posted all of them on a single day. The Single-Day reviewers have rated this product an average of 3.7 while all other reviewers rated this product an average of 3.5. 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.

Warn Deleted Reviews

We discovered a total of 15 deleted Reviews for this product, with an average rating of 3.7. 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:
  1. 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.
  2. We have no information on reviews that were never published in the first place.
  3. 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.

Warn Rating Trend

  • 65%
  • Created over 113 days

We counted 27,198 reviews for this product over the span of 572 days, an average of 47.5 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 71 or fewer reviews on any given day.

However, we see the following 113 days exceeding this threshold:In total, we found that 17,752 reviews were created on just 113 days. This is an excessively high number of reviews submitted on these high volume days.

Warn Brand Repeats

Brand Repeaters


7,165 of the 27,198 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


559 of the 27,198 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.
