I think mounting the Muvi shape on the top or even directly in front looks stupid.
To the side is handy but part of he view will be blocked.
So I moved mine forward a bit...
The emergency charger thing don't work IMHO.
Needs to be charged with mains adapter.
I fitted the bracket thingy with nylon tags on the front of my helmet and it's been fine.I think you get about 80 mins a charge just about covers half of my commute.
My new camera takes two AAA's will test on next commute.
Oppionion or Fact?

IIRC is better used IMHO
Anyway - you're correct - it cannot charge and record at the same time.
