    Like the ring and the way it fits. The app is cool to know heart rate stress and other features. Don’t like that they charge a monthly fee for it after paying for the ring.

    wasn’t worth the money! I had it for 3 days before there was a scratch on it. Every subscription you would benefit from cost extra

    Not worth the price. It’s nice to have sleep data and heart rate but you can get that info with cheaper watches. My battery died after 7 months and had to go through the headache of replacement. At that price and the cost of monthly membership I expect more.
