Best Review

Customers appreciate the wearable computer's sleep tracking and functionality. They find it easy to set up and like the insights it provides about their sleep and heart rate. The app works well and is discreet. Many customers find it comfortable and fit well. However, some feel the monthly subscription cost is excessive and not worth the price tag. Scratches are reported easily, and opinions vary on battery life and color.AI-generated from the text of customer reviews
