This extension was purchased directly from Tethertools to pair with my existing Tethertools hardware. It worked twice in the 60 days I had in the kit. My other Tethertools cables work fine, but this extender just doesn't have it. Tried on imac and macbook pro. Tried all available ports. Simply put, something is wrong with the cable. Judging by other reviews, this has already happened. What about Tethertools?
