    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.

    [Employee of bestbuy] My wife loves this thing. She was inspired from my sister and my dad both having it. Incredibly easy to use. Pairs with your health app on your phone. Worth the investment for your health + sleep.

    I love my oura ring, it gives great health insights. Definitely size up, so you dont have to worry about finger swelling while sleeping. It also takes awhile for it to configure to your body, so you wont have a lot of insights right away. However, definitely worth the wait!
