Are the sites relevant and have any quality?
They are about the topic but the post are just spun different ways talking about how good the product is. I would put the quality just above a scraper site. The posts are just there to sell the product.
The backlink sites are just filled with posts on different topics spun so they could include their sites using different keywords for the link.
