    After having the ring for 5 months now it is faded on the bottom. I messaged Oura about replacing the ring but they said that is normal wear and tear for the ring. So if you workout and lift weights don’t wear it. Other then the worn out look it works perfect for all the health monitoring.

    Within 10 months of owning this Oura ring, the battery charge dropped significantly. In the beginning, the ring would stay charged for 5-7 days. Now, it stays charged for less than 48 hours. I have now spoken with 4 Best Buy customer service representatives and no one has been able to help me resolve this issue with a clearly defective device.

    I love the functions of the ring. It gives great insight on your health. I’ve had it for 4 weeks and have to replace it because of the battery life. It won’t keep a charge

    Bought for my husband to check for Afib, according to the directions you have to also have a subscription. Sales rep should tell you that before they sell it. And it isn't even available yet.

  • Infuriating exchange policy

    Posted . Owned for 3 weeks when reviewed.
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I was denied a size exchange for an unopened Oura Ring and told to return and repurchase instead. The repurchase price was $150 higher. An exchange for the same item in a different size should not cost more, especially when the package was never opened. Best Buy and Oura should have exceptions in place to prevent this type of issue.

    Not comfortable at all and I hate having to subscribe to a service to use something I already own. Not cool. Got with Ultrahuman Pro instead.

    Some people enjoy these rings, but wearing one 24/7 just isn’t for me. I purchased this ring to see if I could track my oxygen levels throughout the day. This ring only tracks at night when you are sleeping. I have sensitive skin as well, and my skin didn’t react well after wearing it 24/7
