Weirdly, there were a number of products with fewer than a couple hundred reviews (books) that were graded terribly but the reviews, upon scanning through them, were actually clearly real, and the majority of them were obviously from people who had bought AND read the book. So, I'm not loving the idea of small authors being totally bombed by this extension.

Additionally, while I was running the extension on a product that hadn't had its reviews scanned through before, I accidentally closed the tab. I was hoping to just restart the process but the extension had already given the product a grade! That's a serious flaw honestly. It's not a fair grade at all.

So while I started out enjoying the extension well enough, my trust in it degraded too much to justify using it anymore. If you choose to use it, just be careful with items with fewer reviews than most popular products---you might have to give them a scan to verify the grade given, which defeats the purpose of the extension.

I insalled this after getting pissed off with reviewmeta.com, which seems to be completely moribund and buggy as hell now.

On the face of it this Fakespot extension is a much better bet. I can see the review ratings right there on the Amazon listings and, with Mozilla behind it, I can be relatively certain its:

A: safe to use.
B: updated regularly.

Unfortunately, the reports generated aren't helpful at all—hence my 2-star rating. The extension will give a product's ratings a grade. But there's no information as to how this grade was arrived at. Even clicking through to go onto the Fakespot site and read the in-depth analysis leaves me none the wiser. It just seems to summarise various highlights taken from the reviews [which, in the case of Amazon, is now done by Amazon themselves anyway].

The extension would be a hell of a lot more useful, if it explained WHY a product's reviews were graded low quality. For example, ReviewMeta [when it works] elaborates on this by showing [for example]; that X% of reviewers have only ever reviewed this product, that X% of reviews contain the exact same phrases that X% of reviewers give any product they review a 5-star rating, etc. etc.

C'mon Mozilla. Act like you're sitting an exam here and show us your working out as well as your answers!
