    Stopped working after just 5 months and scratches very very easily. Having to pay an app subscription is a rip-off

    Quite uncomfortable, due to the limited size, the hardware is not that powerful, with little battery it can’t track all datas in real time. Most of features are enabled by their software algorithms but not accurate. I may want to pay the subscription for their sw but definitely not pay $399 for the small sensors. After 1 week trial, I decided to return it and go back with my Apple Watch Ultra which is so far the best smart device for health tracking.

    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.

    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.

    Not very accurate as far as workouts go. Battery horrible! Have to charge every day. I’ve had it for eight months. Sizing leaves a lot to be desired. Very loose at night. Very tight in the morning.
