Customers are saying

Customers are pleased with the overall performance, phenomenal sleep tracking, and the comfortable, sleek design of this ring. Users also appreciate the long-lasting battery life and the durable, scratch-resistant finish. While most find the device easy to wear, some individuals noted that it takes a little time to adjust to the size and slight weight on their fingers.

    It was great, perfect fit, and everything. The only downside to the O-ring is that you have to pay for a membership, but if you’re OK with that, then it’s a great fit for you.
