AMOVAN Smart Ring Health Tracker, Fitness Sleep Heart Rate Blood Oxygen Tracker Smart Ring, Water Resistant Bluetooth Fitness Tracker Rings, US-7, Gold I really like it, but it’s a bit big on me and I can’t exchange it. Great condition as I only wore it for about a week. App is easy to understand and there’s no subscription fee. Lightweight, comfortable, & chic. Ranked by Cosmopolitan as one of the top 6 smart rings of 2024! ✨
