    This was actually a gift for my daughter, and she loves it. It is great for keeping track of her sleep patterns among other things. She already recommended it to her friends, co-workers, family and her boyfriend. Needless to say, she is very happy with this gift.

    I bought the ring because i thought itd be cool to see health diagnostics aside from the apple watch. Also because my yoga studio has a partnership woth oura - so it syncs the data - that being said, there are times when the workout data does not sync which is frustrating.
