        Oura Ring 4

        I bought this to track my cardio while playing drums. It’s comfortable, great for sleep tracking and the battery life is fantastic.

        Excellent help

        The set up was easy. I sized my ring finger in store and it was accurate to the product. The information provided by the app is helpful in managing my health and routines. This is a great monitor, not for fitness tracking.
