This is angelman's TrustRating, which is based on both the number of reviews angelman has written, and how many other people have voted those reviews as "helpful." It's a way to quickly to determine the value of any single review or reviewer, because it's based on how helpful angelman has been to the Kudzu community.
Not only are the owners and the service representatives great to work with, the service they provide is always spot on. They do what is needed at that time and no more.
