    I think everyone needs one of these it should be standard. Healthy and especially if you healthy you needs to get this it can save your life. It monitors your health. This already save one of my friends doctors couldn’t fine anything out the ring as telling them something was off and sure enough they found she had cancer. Just saying that’s how a little thing like this can save your life.

    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.
