I’ve always had an Oura ring, it’s part of my body pretty much, I track every bit of my day/night with it. Recently I started having issues where it wouldn’t connect for parts pf the day and I’d miss out on calories burned. I contacted customer support and within 12 hours they were sending me a brand new ring at no cost. I didn’t think this great of customer service still existed! It’s well worth the price when that’s the kind of service you get!
