*This is only a Preliminary Report
Our full report will examine much more data, but requires considerably more processing power.

We'd love to run a full report on every product possible, but we had to make a few compromises to get you the preliminary version in under a minute. You'll notice that you can't edit the adjusted rating, we might not have looked at every last review and our user sampling isn't perfectly random.
The Preliminary Report is still an excellent tool and perfectly sufficient in almost all cases. However, for the hardcore data nerds out there (like ourselves), the full report satisfies that craving for precise numbers and hard evidence that the reviews are legit or bogus.
Not only will you receive a notification when you add your email, you'll also bump this product to the top priority in our queue for full analysis - so we'll ultimately be running the full report sooner.
We get it. Ads are annoying and nobody clicks on them anyway However, servers and staff are expensive! We are not going to ask you for money or banner clicks. Instead, we ask that you please share our site. Letting other people know about our tool is much more valuable to us than a few ad impressions.

While this discrepancy is rather large, it is not quite large enough to rule out the possibility of it being due random chance.

We have not discovered any deleted reviews for this product.
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.
