Ultrahuman Air Size 5 Activity Smart Ring Tracker

Ultrahuman Air Size 5 Activity Smart Ring Tracker. Some signs of wear but only used for a couple months as I decided I wanted to wear it on a different finger so got a new size. Similar to the Oura ring, great for workouts and runs, women’s health and fertility tracker, accurate temperature and heart rate measurements. Sleep tracking and insights. Love this ring! Free subscription lifelong subscription too!
