Warn Rating Trend
-
- 43%
- Created over 12 days
We counted 141 reviews for this product over the span of 706 days, an average of 0.2 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 3 or fewer reviews on any given day.
However, we see the following 12 days exceeding this threshold:In total, we found that 60 reviews were created on just 12 days. This is an excessively high number of reviews submitted on these high volume days.

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.
