Was that the current Oura or the original model? The original model looked huge, although I never saw one in person. I find the current model to be perfectly comfortable (wearing it now), although it is thicker than a typical wedding band or something.Interesting. We tested the Oura and found its thickness uncomfortable. It seems to be taking the world storm though.
I'm really hoping Oura comes up with a payment solution, and then it would do everything I want.
