    I love my oura ring. I wear it everyday. As someone who use to not wear rings, I was comfortable wearing it after 2 days. I always am scared it’s gonna slip but it never does even in water. I love the app, def a great buy! It can scratch up but I have it in gold and you can’t really see it. Plus you can buy ring covers on amazon

    LOVE LOVE LOVE! It is so worth the money. It is comfotable and light and you barely notice it after wearing it for a while. The one thing I will say is that you have to pay for the subscription to Oura but it is so worth it. The data you will get will change your day-to-day living and choices. Would definitely repurchase.

    Absolutely love my Oura Ring! The sleep tracking alone has been a game changer. The insights are detailed, easy to understand, and actually helpful for improving my recovery and daily performance. The design is sleek and comfortable I forget I’m even wearing it. Battery life is excellent too. Highly recommend if you’re serious about optimizing your health.

    I had gotten myself an oura ring and when my husband saw mine he wanted one for himself so we went and got him one and he is absolutely obsessed! I use it for cycle tracking but my husband loves seeing his sleep patterns and calorie burn. We will definitely keep buying Oura rings as they continue to perfect they’re technology.
