    The ring got stuck on the charging band and no one in Oura customer service could assist so I took it back. That said, Best Buy was awesome -- the ring came quickly and they also tried to help me but couldn't - they took it back right away. Thank you, Best Buy!

    It does its job but I think it’s a bit overpriced for what it is. I also don’t like that I have to pay monthly for a subscription.

    I think it's an overrated device, yes you can track something, but! Heart rate and stress levels for 500 bucks, really? I thought there were more useful features, but in the end a very overloaded app and very little use. I don't understand why I need it.

    The Oura Ring 4 is a decent enough wearable, but I would not advise buying the stealth version. It scratches very easily and does not retain the natural matte finish very well.

    I really enjoy my oura ring and it gives me valuable health data, however it is getting replaced right now because the battery life has flaws.

  • Frustrating Waste of Money!

    I literally never write reviews, however this is an expensive item. First the Pros - great data and app and REALLY want this to work. Now the Cons - the ring keeps on failing. I'm currently about to get my 4th replacement ring since my original purchase in October 2024 (3.5 months!). All 3 rings I have had have all lost their ability to connect to my phone and won't charge - essentially they just die. Oura response has been "we have discovered an issue with your Oura Ring." At this point I wish I could take the ring back to Best Buy and get my money back. Why is Oura releasing a product that is clearly defective!
