    Overall i do like the ring! Myself personally, think its a little thick. Although from my understanding it’s significantly thinner then the last generation. It charges quick and over is easy to use! I do wish there was a better way to find it when you lose it. So i use an apple watch too and tbh im more concerned hsvjng my ring on vs my watch. I will say it scratches maybe thats totally normal for rings in general im not sure. Overall its a goid product!

    I love this ring so much! J pay so much more attentjon to my health and my sleep. It catches everything about my stress levels and gives me advise when it gets high. I personally think the activity charts are a little off but it doesn’t bother me too much

    Love how I can tell if my body responds to a late meal or high sugar meal by noting elevated resting heart rate. I am using this ring to become more in tune to how my body reacts to various foods and rest…or lack thereof. Very accurate.

    Love the features and battery life is pretty good. Can go days without charging. After just a few months of having the gold version of the ring a lot of scratches and more tarnished than I thought it would have. Still would buy again.
