Bests & Worsts Reviews from Amazon

Product performs as described. Wear it in the shower with no issues. Only improvement would be ability to set upper heart rate range to get alarm when heart rate is over a specified range. I have lowered my review as the Ring has lost color on underside within 4 weeks. This was noted by other reviewers. I reached out to support 4 days ago and have received no response. I will update if there is a response from customer service. Customer service is shipping me return label to exchange for slate grey ring which hopefully will hold up better. Sent back Ring 10 days ago for exchange. Have not anything. No response to my emails.
