Query: The worst

This is a terrible product. I am surprised that amazon even allows it on their site.It does nothing has noflexibility what so ever and once you let them know that. They just automatically send you another one andcharge your account without ever even giving you any notice at all. Bad buissness for a bad product. I am sovery disappointed in Amazon for even selling this item.
