Hey RM community - in the spirit of full transparency, I've decided to make a public announcement...
It's been a wild adventure since launching the site 2016, however I've decided it's time for me to move on. I'm now searching for a successor to ReviewMeta. The main concern is making sure the site will stay true to its roots - helping provide transparency to an industry that's increasingly darkening.
If you know anyone who would be interested in taking over this project, let me know here. You can also read more about why I've decided to move on and what's next for me.

- Created over 45 days
We counted 4,849 reviews for this product over the span of 832 days, an average of 5.8 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 15 or fewer reviews on any given day.
However, we see the following 45 days exceeding this threshold:In total, we found that 2,754 reviews were created on just 45 days. The reviews on these high volume days have rated this product an average of 4.3 while reviews from other days have rated this product an average of 4.0. 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.
Fail Unverified Purchases
Unverified Purchases
245 of the 4,849 total reviews for this product are unverified purchases. The unverified purchasers have rated this product an average of 3.5 while the verified purchasers have rated this product an average of 4.2. 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.
Unverified purchases may be the result of Kindle Unlimited readers, buyers who didn't pay full price, or reviewers who did not purchase the product at Amazon. Read more about our Unverified Purchases test.
Fail Suspicious Reviewers
Suspicious Reviewers
One-Hit Wonders
535 of the 4,849 reviewers have only reviewed this product. While this is more One-Hit Wonders than we'd expect to see, it does not appear to have a significant impact on the overall rating.
Never-Verified Reviewers
69 of the 4,849 reviewers have never written a verified purchase review. The Never-Verified Reviewers have rated this product an average of 3.5 while the reviewers who have written at least one verified purchase review rated this product an average of 4.2. 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.
Take-Back Reviewers
772 of the 4,849 reviewers have had at least one of their past reviews for another product deleted. This is an excessively large percentage of Take-Back Reviewers which may indicate unnatural reviews.
Single-Day Reviewers
51 of the 4,849 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 4.5 while all other reviewers rated this product an average of 4.2. 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.
Fail Word Count Comparison
Word Count Comparison
-
- 31%
- Have an overrepresented word count
In the graph above, we can see the distribution of review word counts for this product and the expected distribution for this category. We see the following 1 group with a statistically significant greater concentration than what we'd expect to see:In total, we found that 1,508 reviews (or 31%) are within an overrepresented word count group. These reviews have rated this product an average of 4.3, while all other reviews have rated this product an average of 4.1. 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.
Fail Phrase Repetition
Phrase Repetition
Reviews that contain one of these phrases are NOT necessarily devalued; read more about how this test works here.
277 of the 4,849 total reviews for this product use substantial repetitive phrases between them. These reviewers have rated this product an average of 4.6 while reviews without substantial repetitive phrases rated this product an average of 4.2. 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 Deleted Reviews
Deleted Reviews
We discovered a total of 113 deleted Reviews for this product, with an average rating of 4.3. 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:
- 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.

Warn Brand Repeats
Brand Repeats
Brand Repeaters
1,293 of the 4,849 reviewers have reviewed other products for this brand. While this is more Brand Repeaters than we'd expect to see, the discrepancy in ratings between the Brand Repeaters and non-repeaters isn't significant enough to rule out the possibility of it being due to random chance.
Brand Loyalists
115 of the 4,849 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.
