I think there are some people who give an unbiased view of a product regardless if they are getting paid to review it or not. It really depends on the person. I kind of follow Christopher Schwartz's "Lost Art Press" blog on WordPress and he will occasionally mention his own products. I have some of his products and have found them to be great products. There is a great deal of value in having someone review your product honestly regardless whether the review is good or bad; if it is bad then your product needs to be improved.
