If I have received a product as a PR sample I will write this in small text at the very end of very start of the blog post. This does not hinder my opinion. I write many reviews for companies and as honest as they come- If I don't like something I will say. So far I have never been sponsored to write a post, mention a company or anything of the sort. If I ever do I will clearly disclaim this. Any links given during a review are not affiliate links.
