- Created over 112 days
We counted 7,100 reviews for this product over the span of 2,461 days, an average of 2.9 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 10 or fewer reviews on any given day.
However, we see the following 112 days exceeding this threshold:In total, we found that 1,496 reviews were created on just 112 days. The reviews on these high volume days have rated this product an average of 4.7 while reviews from other days have rated this product an average of 4.6. 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.

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.
