In the video (maybe an update) it said it worked when the child protective coating was scraped off. (Editors note at 2:27)

It sounds like a Duracell issue to me, maybe it was a nonstandard thickness of the coating that was interfering? We will see if this becomes an actual issue, it may be a one off batch and not an issue in the long term.
