    • Size is good. Feel comfort wearing it.
Size: #9 Color: Gold
Size is standard and fit. Super comfortable and easy to wear, especially for sleep—barely notice it’s there. The sleep tracking is detailed and the data feels consistent over time. Great for monitoring overall trends and daily health

    • Great smart ring
Size: #7 Color: Gold
Value for money is great. I love not needing a subscription to get data. Functions great. I wanted to track my blood pressure at night while sleeping. It seems accurate. So far seems durable. It is not supposed to get wet. Be sure to check your ring size on the finger you will wear ring on. I had to send the first one I ordered back and get another size larger. ... show more

    • Best sleep tracker I’ve used!
Size: #10 Color: Enamel color
After using this smart ring for several weeks, I’ve found it to be a fantastic, unobtrusive alternative to a traditional smartwatch. The sleep tracking is the standout feature, providing highly accurate data on my recovery and heart rate variability without the bulk of a screen on my wrist. It is incredibly lightweight and comfortable enough to wear 24/7, and the battery life easily lasts nearly a week on a single charge. While the exterior has picked up a few minor scratches from daily wear, the deep health insights and seamless app integration make it a worthwhile investment for anyone looking to monitor their wellness discreetly. ... show more

    • Won’t sync to my phone
Size: #7 Color: Gold
The ring started out ok tracking all areas and syncing to my phone. Unfortunately after only a few weeks it stopped syncing to my phone. I deleted and reinstalled the app but still no luck. It’s being returned.

Size: #7 Color: Gold

Sleek, lightweight, and comfortable—looks more like jewelry than a tracker. Basic features like steps, sleep, and heart rate work well for everyday use.

    • Does as expected! Scratches easily.
Size: #9 Color: Gold
Review Image by Meredith Doubrava
The ring does what I wanted it to do which was track my sleep since I don’t like wearing my Apple Watch to bed. It has monitored blood pressure, steps and everything else very accurately when compared to my watch data I will say that it was beautiful when I first got it and it does scratch so it’s going to look worn fairly quickly. I’ve been wearing it daily for less than a week and it has some obvious signs of scratching, even though I haven’t done anything major with it other than that. I do love it. It’s great for the purpose! ... show more

Review Image by This product is used in nursing homes which is where I heard about it I started to develop rashes and I will use it at night time and it goes away pretty much the next day it is worth it even if the consistency of it is thick it's so worth it
Very comfortable to wear ring the app is easy to use. Tracks stepps, sleep, hr and body temperature and monitors BP. And stress level which is under HRV in the app. Would get it again.
