There are many "fake review" sites on the web. Their absolute goal is to have listed in the search engines for the keywords of their competitors plus the term "scam" or "review ".This black hat method is completed to have traffic in an underhanded way. You can spot them a distance away as the fake reviews of their competition are often all negative and they've an url to their own site somewhere in the review. Basically, it's the old "every one of these sites are bad, but here is a good one" routine.
My advice for you would be to IGNORE those fake reviews and get your information directly from the source. There's more than enough informative data on our sales page to create an educated decision without having to resort to incentivized fake review sites for bad information. Real reviews are impartial and have no links to money website making sites.
