    This is a replacement of older model (version 2). This model is thinner and lighter in weight.

  • Infuriating exchange policy

    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.

    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

    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.

    This ring is well built. Very high quality, but could use some design improvements. It’s a bit chunky, and uncomfortable on any finger other than the index. Ultimately, I give it 4 stars as a product. However, it gets 0 stars for requiring a subscription to get your data from the product you paid for. There’s nothing special about the app to warrant the subscription when you look at the competition. This lands the product at a 2 star rating from me, I’ve returned this, and went with the Ringconn Gen 2. It does pretty much everything the Oura 4 can do. However the Ringconn is 25% cheaper, has no subscription, is smaller, lighter, more comfortable, has twice the battery life, and comes with a charging case.
