Hopefully version two is rechargeable.

This is version one, I'm not particularly worried as I will probably upgrade to version two by the time the battery runs out.

I dunno. If you need to record your thoughts often enough that you're wearing a smart-ring to do it, then it seems like you're going to burn through the 12 hours of recording time pretty quick.

Probably. Also, if I/we don't buy version one, there may not be a version two.
