    Would highly recommend. It tracks my stress and gives tips to relieve it. It also knows when im getting sick so I can quickly take action. I also love that I can take a shower and wash my hands without taking it off.

    I received it on release day. It’s only been a few hours since I have had it. But I love how there is no longer any bumps inside. It appers thiner, and well constructed. I love the silver, it looks so good with my white gold jewelry! So far no complaints!

    Got this because the Fitbit I had fell apart after a lap and a half in the pool when I tried using it for swimming. Unfortunately, the Oura ring only read the first time I used it swimming. Since then, I've had to manually enter each time that I swam. Does not read my activities at all, I am always entering tasks/activities manually after the fact. Does not seem to be designed for people who work nights. Even with my entering when I work, it still tries suggesting I sleep during my work hours. And has a difficult time properly registering my sleep. And now, after 2 months I am having the problem of my fingers fluctuating in size. The ring goes from almost being too tight to slipping off my finger, Recommend you get a ring that fits in the middle of sizing various fingers. Then, as fingers change in size, you can switch the ring to the best fitting finger at the time. Ring is tough. Swim with it twice a week. Wear it at the gym and has not gotten scratched or scuffed yet.
