[This review was collected as part of a promotion.] DON'T BUY IT! I bought my ring in the spring and already will not hold a charge longer than 7 hours. I have done multiple resets on the ring, checked all settings to ensure other apps are not draining the battery and still will not hold a charge. Since it will not hold a charge longer than the 7 hours, i cannot even use it to gather data on my sleep, limited thru the day as well and have to charge it just to even track steps. Buy the Oura!

I have my ring for around 5 months. Very happy with it in the beginning but starting one month ago, the battery drains very quick. It used to last 3 to 4 days but now I have to charge it 2 times a day, which is so frustrating! I tried the troubleshooting guide, drain it for 4 days and charge it. I'm using the chill mode. I don't know what other solution to try. It's a bad value for the money I spent.

[This review was collected as part of a promotion.] Valuable data points are being collected. Hardware design is very minimalist and can easily blend with other jewelry. Battery can be prolonged in the future but the chill mode has immensely helped with battery life. Just because I have garmin 965 as my daily driver I sometimes forget to charge my ring after 2-3 days which I never do with my garmin watch.

I have been using the ring since past 2 months and it's been great experience so far. I am able to take actions based on various data insights like sleep, movement, caffeine intake etc. Thanks Ultrahuman team.

[This review was collected as part of a promotion.] I bought it 6 months ago and I'm wearing it 24/7, specially to monitoring my sleep and I'm very satisfied with all the data it collects and how the app shows and explain everything.
