    I’ve had my ring for about 3 weeks now and I am loving it. It’s still getting use to some of my habits but for the most part it’s been tracking great! I love that it senses your body needs rest or that it’s fighting something and is so accurate on sleep etc. I’m hoping this will help me with my health in 2026! I would definitely buy again!
