Type in "https://usenetreviewz.com/" without the quotation marks and add the name of the Indexer review you'd like to see then "-review" without the quotation marks.
If the Indexer's name has more than one word, be sure to add hyphens between the words.
For example, say you had heard of an indexer called nzbKing and you wanted to know more about it. You'd type in "https://usenetreviewz.com/nzbking-review/" without the quotation marks and presto! You have a review that's not posted on the regular list of indexers.
The review for that Indexer will be shown if it exists in their database. Usenetreviewz has many reviews of sites not listed on their 'Best NZB Sites' page.
