    Love these but still need more. I am concerned about the battery part coming out if not installed a particular way and worried when I move would i have to repurchase new ones or does the sticky tape let me replace it? Basically what happens when I want to move?

    I couldn't tell you anything about these as we bought them for a Christmas gift. Best Buy would not stop emailing about reviewing this, so here it is. You would think they woud know most things purchased between Thanksgiving and Christmas are more than likely gifts for someone else.
