Fake Amazon Reviews
Important when looking at reviews on Amazon: click on their profiles and see what else a person reviewed.
I find a lot of reviewers are fake, and are really just sock puppets of the person selling the item.
When the person reviewing the item only ever reviewed this item, or reviewed only items from this seller, it is likely a fake.
Here is an example: http://www.amazon.com/gp/cdp/member-reviews/A2VPSIZ4K6A5EV/ref=cm_cr_dp_auth_rev?ie=UTF8&sort_by=MostRecentReview
