I just figured, that no matter how good a quality the product you are selling is, its always a good idea to protect yourself against liability.
I purchase my goods from china, and there is no way for me to tell if what I am selling is 100% without any issues. There would be no possible way for me to check the products as they are electronics, and I cannot personally vouch for their safety (even though I assume there is no issue).
I am not sure if ebay buyers have to agree to certain terms and conditions when they sign up to say that they cannot hold another party responsible.
I come from a background where health and safety (at work) is very important, so I have grown up with this, and I want to make sure I get my due diligence right just in case something should happen.
