    Reading up on this ring as much as I could before I purchased it was one thing, but going to a Best Buy store and hearing a sales person tell you about it, was better than just reading about it.

    I got this ring as a gift for my wife and she loves it. The app is miles ahead of other fitness/wellness apps and the sleep tracking has been a cool feature to have as wearing a watch to bed isn't comfortable.

    It is a little too bulky and the oura app is easy to follow. I’m not sure if I would recommend to a friend just yet. I need a little mire time wearing it and using the app.

    I love my Oura Ring. It tells me when I don't sleep well, when I have something abnormal going on in my body. Many perks with this ring. I do wish it would last longer when I charge it.

    Thank you! The battery life in the Oura is AWESOME. I switched from Ultrahuman and the battery life on that ring is horrible. 60% battery loss in 12 hours. With the Oura in 12 hours I only lost 10%.

    Only Buy for Sleep Tracking

    This ring is a mixed bag. What it does well is track sleep. It is the best i have found at matching what i feel upon awakening. I have a Sleep Number bed and it will often give me a good score when i perceive i have had a terrible nights slerp. The ring is really bad at tracking workouts. DO NOT buy this for fitness tracking. Get a cheap Fitbit or even better a Garmin watch. The ring itself has very little ability to track workouts. I was using Strava to export to Oura, but even that has stopped working. I took another star because not only did my original ring fail after a few months, but my wife's is also starting to fail, often dying after just a day or two and refusing to synch. Overall, probably the best ring, but only buy if you prioritize sleep tracking.
