    I love this purchase. I’ve had it for about 8 months now. It has given me insight to a lot of my body’s critical metrics, and improved my lifecycle. I recently noticed the battery draining quickly, and the support team was able to immediately diagnose the problem and is replacing it for me.

    Went in store for sizing and placed the order online. Shipping was on time.My wife loved this ring. It is very informative and helps her keep on track with her goals. I wasnt very informed on this ring at all. I just knew she wanted it. And from what ive seen the ring does more than i expected. Overall very satisfied with the purchase.

  • Great Alternative to Apple Watch

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I absolutely love this ring. I quit wearing my Apple Watch because of the bulkiness and was looking for a good alternative. After wearing the ring for a while, I wish I would have sized down. There’s definitely som discrepancies between the sizing kit and the ring itself. I use the Oura ring with Natural Cycles and I love how everything transfers over easily.
