Fail Reviewer Participation

These reviews have rated this product an average of 4.5, while all other reviews have rated this product an average of 4.1.

Warn Deleted Reviews

We discovered a total of 362 deleted reviews for this product, with an average rating of 4.8. 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

  • 63%
  • Created over 202 days

We counted 10,061 reviews for this product over the span of 1,263 days, an average of 8.0 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 19 or fewer reviews on any given day.

However, we see the following 202 days exceeding this threshold:In total, we found that 6,309 reviews were created on just 202 days. This is an excessively high number of reviews submitted on these high volume days.

Warn Brand Repeats

Brand Loyalists


237 of the 10,061 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.
