Maybe your experience is different from mine then. My device was inaccurate enough to be useless. Further there doesn&#x27;t seem to be any allegation that people are expecting it to have a medical or diagnostic level of reliability. That seemed to be a throwaway line in OP&#x27;s article, not something core to the lawsuit. As far as I can tell from other news sources, they are suing because it can&#x27;t read heart rate for crap.
