    It works well but is not that comfy. Would also like a gps and a tint speaker to make noise when losing it

    This ring was okay, but I need a ring that could track my oxygen levels all day. This ring only tracks once at night. Due to health issues I could not benefit from any of the other benefits at this time. Overall, I think this ring is good as long as your do not need to track your oxygen.

  • Disappointing Lifespan

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

    Great product while it works! Very interesting data points from daily sleep tracking. Unfortunately, the battery in mine died after around 10 months. To me that's far too short a life span for a product at this price point. Maybe the current generation is better but I don't think it's worth the cost to find out.

    Its small size makes it better than the Apple Watch and it does a better job at tracking vitals.

    I like it, it's just difficult to get all the stats. There is no weekly summary, 30d summary, etc. Its truly just a daily tracker. Be sure you get the sizer or try on in person. And follow the guidance of sizing down if you think you are in between sizes
