    Love the ring! I got the ceramic for the fact of being very hard to scratch, and so far that has been true. So glad to have spent the little extra.

    I love my Oura right! It took me a while to pull the trigger on making this purchase. I bought it to celebrate passing a huge credentialing exam. I haven't regretted it for one second. It tracks so many metrics and I trust the app with my data versus the competition.

    Bought the ring specifically for tracking sleep and heart activity. And it does what it intends. Only downside is the subscription.

    Love the ring and the app. I gave 4 stars because I’ve only had the ring for a little over a week and it is already scratched in a couple of places. It shouldn’t be that fragile. I have to take it off when doing housework, washing dishes. Disappointing since the ceramic costs more than the metal - it should be more durable.

    Got my ring 3 weeks ago. I was recently diagnosed with RA and it has already started helping me track when I’m about to have a flare up. Helps me understand a lot of what my body goes through each day. The ceramic white is so nice and goes with everything. I have small hands so it’s a little bulky for my fingers but I still love it.
