You would think the idea of some site would be to provide a objective review. I mean I know why you have the paid to blog product review that a company wants. But you would think an Internet Company would provide a honest and frank style site that did give a critical view.
I mean you have the consumer report type sites and magazines but I believe you have to subscribe to them. Consumer reports is usually dead on most of the time and always informative about any product.
ConsumerReports.org
So if it is worth it too you financially to invest in a membership then I would recommend them. Although some local libraries have past magazine issues for free.
