My husband bought me this tool in 2008 and it has the same fly-apart head construction that other reviewers describe. Mine even broke a window. The tool is so non-functional that I don't see how B&D could have put it on the market. They clearly didn't test it themselves. When it isn't flying apart, it consumes cutting line as if it were spaghetti. I would NOT buy another string trimmer from Black and Decker.
