Analysis Details

The unverified purchasers have rated this product an average of 4.5 while the verified purchasers have rated this product an average of 4.3.

Warn Deleted Reviews

We discovered a total of 295 deleted reviews for this product, with an average rating of 4.4. 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

  • Created over 121 days

We counted 35,185 reviews for this product over the span of 1,376 days, an average of 25.6 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 44 or fewer reviews on any given day.

However, we see the following 121 days exceeding this threshold:In total, we found that 28,856 reviews were created on just 121 days. This is an excessively high number of reviews submitted on these high volume days.
