    The sleep data is my favorite feature. I never knew what kind of sleep I got or how much. I also like the way it tracks my activities. I no longer need my Apple Watch for that so I can wear any watch I want.

    Absolutely a beautiful finish. I think it is worth spending a little extra to get the gold finish on this. It looks like real gold and I get lots of compliments on it. As a woman, it compliments my other jewelry as my favorite is gold. The only con I’ve found is that it does scratch easily even when doing daily tasks

    I was super excited about this purchase as I want to take my health to the next level but I don’t like that I have to constantly go into my app and confirm the activity. I wish it would just do it by itself. And also if it had a more in tune and sophisticated tips and tricks when it comes to bettering a portion of your health that you struggle with. For example, I cannot stay asleep but it just tells me that and that I need to rest but no real tips.

    It is a little too bulky and the oura app is easy to follow. I’m not sure if I would recommend to a friend just yet. I need a little mire time wearing it and using the app.

    This ring has been very helpful. It alerted me when my heart rate was unusually high and fluctuating. As soon as I noticed, I contacted my primary care provider and began addressing the issue. The ring has also helped me improve my sleep. I’m truly grateful to my daughter for buying this ring for me.

    Really enjoy the feed back it gives about sleep. I like this a lot more than the Apple Watch to track calories burned. Only thing I’m not thrilled about is that the battery does not last a full 8 days.
