  • Tolerable to wear at night for sleep staging

    I bought this to check heart rate and to track sleep data. I like that it's tolerable to wear at night. I'm very sensitive about wearing things like this at night. It's been interesting to see the sleep info, heart rate over time, and HRV. The activity sensor is showing me I'm actually much more active during the day than I thought I was. Would buy again.

    This ring has been a game changer for sleep and fertility tracking. I am so glad i went for it. I know more about my body and can let myself relax when it’s warranted. Their customer service is also great as i had a bad battery in my first ring and they sent me a new one quickly and for free

    I purchased this in early December and have been using it for over a month and a half. I purchased the size kit and picked my size and I would say it feels less bulky than the size kit, but otherwise true to it. I think it does a great job with what it tracks and I have no reason to believe it’s inaccurate. Overall does what I want and I have no complaints , besides if you want another charger it’s $60. I also find the app easy to use and connect to other apps just fine

    I have had this for just shy of a month, and this ring is amazing so far!! No complaints at all! I love being able to see how stressed I am through the day because it makes my exhaustion a little more understandable at the end of the day! This thing literally tracks everything, it’s amazing! I normally take my ring off and set it on the charger when I shower so I can’t comment on battery life.

    I love how this ring tracks my sleep patterns. It even tells me that I should get more rest when needed. I used to have a Fitbit and got tired of not being able to where my watch as jewelry. I love this ring so much more because it's an accessory for me. Downside is there's a $5.99 monthly fee but find that the feedback I'm getting is a good investment in my health. And can use HSA dollars.

    My only complaint is the scratching that occurs with a few months. I routinely take my ring off when I’m showering, washibg dishes, even lifting things I’m worried will scratch it and it still has scratches. It has also already tarnished/changed color so that kind of stinks. BUT I love all the things it can do. It’s so amazing all the metrics I can see.

    The Oura ring is amazing, I love it, I was thinking about this ring for a long time ,but I decided to buy it, so I recommend this ring to everyone. If I could, I would give ten stars instead of four.
