$20 · DDR mats and karaoke microphone

*** I cannot get these items to work with my Xbox 360! I got them new from Amazon a few years ago but just could not for the life of me figure them out. They said they were compatible with Xbox 360 - they just have a usb connection so who knows. They’re in great condition as they’ve never been used but it’s a gamble as to whether or not they will actually work. New dance dance revolution mats - $10 for 2. Karaoke microphones $10 for 2
