A battery life of 10 to 12 days is pretty good (in reality it may only get 7 days), with a battery charging case providing an additional 150 days of power! But that is still longer than the Oura ring. Costing less than an Oura and also being subscription-free are more positives.
It does apparently sync data to Google Fit, but not to Strava. So I’d be sure to check properly what services it syncs to. Today, the ideal is to sync to the global Apple Health and Google Health Connect services.
I’d certainly not consider buying a ring with a monthly subscription payment, so next time around I’ll be comparing this ring with the Galaxy Ring and other similar contenders.
