As the title suggests, this is pretty hard to screw up. Before sticking the glue, make sure you don't cover the entire opening of the camera, otherwise line up the hole with the hole, remove the tape and stick it on. The door slides in and out properly and feels secure on a laptop. The packaging I received was questionably lavish. It looks like it was meant to be in a set of 6, only one of which was included. I think it's good in terms of efficiency, but they could save some money and use simpler packaging.
