    The ring was very accurate when comparing it to other tracking devices for fitness. I do believe the battery isnt as great as it was made out to be. Overall though, the ring is pretty good.

    I like my Oura ring but I feel it isn’t as easy to keep it looking nice as I would like. It shows wear easily. I know I can buy a ring cover but I returned one (diff vendor) because it was so bulky. The app isn’t as user friendly as I would like too—it’s not easy to look at past data on the app.

  • Oura Ring - Excellent for Sleep & Recovery

    This is the second Oura ring purchase. I’ve been using the Oura Ring for over a year now, and I’m honestly impressed with how much insight it gives me into my sleep and recovery. The ring itself is sleek, light, and looks more like jewelry than tech. I actually forget I’m wearing it most of the time.

    Bought as gift. Best Buy shipped it to another person in another state. To date, I still haven’t received it. Bummed. Best Buy would get no stars - but I hear the item is great.
