Analysis Details


Fail Suspicious Reviewers

Take-Back Reviewers


4,153 of the 45,464 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.

Single-Day Reviewers


938 of the 45,464 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 4.7 while all other reviewers rated this product an average of 4.5. 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 Rating Trend

  • 78%
  • Created over 459 days

We counted 45,464 reviews for this product over the span of 1,884 days, an average of 24.1 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 42 or fewer reviews on any given day.

However, we see the following 459 days exceeding this threshold:In total, we found that 35,578 reviews were created on just 459 days. This is an excessively high number of reviews submitted on these high volume days.

Warn Brand Repeats

Brand Loyalists

While this is more reviews from overrepresented participation groups than we'd expect to see, these reviews do not appear to have a significant impact on the overall rating.

Pass Deleted Reviews
  • 0
  • Reviews have been deleted
We have not discovered any deleted reviews for this product.

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.
