Excellent video, and funny soundtrack! I've never heard of the "snap adapter"....will have to Google that.
It's a weird accessory that Dji came up with for the Mini and this is not the advertised use.

(I've since tried it in full daylight and it's not bright enough to be of any use). This is the link for the video review I saw:
