Product reviews are a great online marketing tool that are being used in the 21st century. They are nothing but customer summaries of products. Once a customer uses a product, he conveys his satisfaction or dissatisfaction to other potential customers who are looking to buy the product.

Paid reviews are when the company hires bloggers or reviewers to test the product and review it. Unpaid reviews may result from happy or dissatisfied customers looking to spread or rant about the product. But what is important here is that despite the reviewers being paid, the reviews need to be completely honest. Honest reviews are not only a boon to the customers, they are also a tool for companies to revaluate their products.
