    since I started using the Oura Ring, the fitness-tracking wearable has served me several ways in my day-to-day life. But one thing has remained the same — more than anything else, it’s a conversation starter.

    I ordered the wrong size on my first one, the sizing is a little different than actual ring but once I got it I loved it!!! I wonder how long it will function but I have had it almost two months and I love it… I use it in cold plunges, hikes cooking cleaning etc and it lasts great!! I don’t use lotion or anything in my hands I take off if I use hand sanitizer but it is worth the effort for the information it gives you about what your body is doing!!!

    No issues. Does exactly what it says it tracks using the app. I wash my hands with it on with no issues and doesn’t cause any rashes. I have the silver, shows mild wear but only if you look close. Happy with my purchase overall
