Title: Crap replacements
Review: These are not even worth the effort. They do not last more than a week before the heads start to get loose and are unable to spin with any pressure. AVOID at any cost and go for something in the normal price range. The warning that came with the order should have been my first sign of what was to follow. It said that some have been found to be defective and to return them if it happened. ALL 4 were bad!
