The feedback collections on Ebay are a great record of a seller or buyer’s overall trustworthiness, but Ebay does not allow users to analyze the feedback to best effect. For example, there is no easy way to find negatives or neutrals through the Ebay site proper. But this Web site, Toolhaus, has a tool that allows you to pick out bad feedback. You type in the Ebay ID and check the results. You can find bad feedback given and bad feedback received.
