Same here. I mustve been tired when I impulse added XBox accessories from my "save" list. The pictures were clearly there. no misconceptions as to what you're buying. But for 5$, cut some velcro, Scotch/3M fasteners and apply as needed.
I had already had my Wii sensor discreetly mounted at a natural level right under the TV on the TV unit. another 5 seconds of thought and I shouldve realized I could just repeat that application on the Kinect and dont even have to add anything to the sensor.
Ultimately, for 5$, it's overpriced, and I left my wii sensor where it always was, and sat my Kinect on top of my TV unit since it could auto angle downwards. I'd rather not have my wii sensor up there with it, awkwardly having the player point upwards above the TV to control anything.
