Nice review.
There's an answer to Yodu's question about case vs band coloration missmatch who was asked a few days ago. I hope he will look at this vidéo review.
I'm still not sure of how the battery is saved by counting seconds by two at once, but interesting enough to be noted.
By the way, is your daughter OK ? The Vault snaped quite hard at the end of the video. She might have lost a fingertip or two. I would count them to verify ...
