 I have made several changes to the Disadvantages section. The references for this section were terrible - citing a fur store, and an Answers.com source which mirrors Wiki content and provides only circular references to support it. I have also changed some text to avoid plagiarism from the source. I'll look for new refs when I get a chance, but have inserted citation needed tags until then. Please feel free to insert reliable refs or change text to reflect reliable refs.
