Is the Oura a good purchase? I've been really eyeing the health benefits of the Apple watch but there's no way I want a portal into the digital world that's a flick of the wrist away. It's bad enough with the phone pickups.
The battery life is very good, I typically get several days to a single charge, which is far better than the Apple Watch. But most importantly it's comfortable to wear during sleep - indeed it takes the majority of its measurements only while you're sleeping. YMMV but there's no way I can wear an Apple Watch to sleep, while the Oura ring works perfectly. I've worn the last two generations of Oura ring and would definitely recommend.
