I bought this used on Poshmark last year and really enjoyed using it for about 6 months. I learned some amazing things about my sleep and have made big changes. It’s very interesting to try out. However, I’m ready to switch back to just using my Apple Watch. Priced to sell! I don’t think I have the box anymore- but I’ll check. It comes with the charging cord for sure. It works great! A super bargain for someone wanting to try out the Oura. Sleek Oura ring in silver. Comes with a black charger. Perfect for tracking health metrics.
