Died after less than 2 weeks
Wore mine for 11 days and noticed the app hadn't updated my latest data. Found the ring to be completely dead, it won't charge and the app no longer detects it. So far Customer Service have only told me to try different charging cables or power outlet and clean sensors, all of which I'd already done anyway. I better get a refund or replacement otherwise the bad reviews will be posted wherever I can. Watch this space....
