Prevention Circul Plus ring review: in pictures

Wearables today capture an amazing amount of data about our bodies and one ring that captures more than most other wearables is the Prevention Circul Plus ring. It's affordable, a bit clunky, only measures for a day or two, but if you have a desire for accurate measurements and prefer the ring form factor then you might want to consider it.
