Brand new Oura Ring 4 in Size 7–please note it does not come with the original box or a charger. I just got this ring two weeks ago but the battery is **FAULTY** meaning you have to charge it every 2.5 days; it does not have a battery life of up to 8 days like the website promoted. I got a new replacement ring, so I am selling this one. Brand new condition. Everything else works perfectly as far as tracking on the app, it’s just the battery life that isn’t as good as it’s supposed to be. It wasn’t a pain for me to charge it every 2.5 days but I got a replacement because it was under warranty and for $500+ dollars the battery should last longer.
