  • Impressive quality
Size: 7 Style: Silver
I was pleasantly surprised with the quality of this ring. It just looks like a regular ring and the best part is it is very comfortable, you won't even know you are wearing it. It's easy to connect to my Android. This is going to be very helpful to monitor my vitals on a regular basis.

  • Avoid this product.
Size: 11 Style: Rose Gold
I really wanted to like this ring. The price and functions seemed very appealing. HOWEVER, there were issues that made it completely unacceptable. First of all, It required an app interface that asks for far too much personal information having nothing to do with the product. For instance, it wants access to your contacts list and your camera. That's a hard NO. Then there was the functionality. Binding the ring to my phone caused immediate problems that no amount of troubleshooting could fix. The way it accesses bluetooth caused immediate problems with other apps. This is a big issue if you're like me and listen to podcasts, music, and audio books on your phone. As soon as I installed the ring and app it caused repeated interference in other apps such a Spotify and Audible. The ring/app/bluetooth caused constant dropping of media I normally consume every day. My phone is a Samsung Galaxy 24, a new-ish and reliable device. Once I removed the ring and its app, the problems vanished. I returned the ring and advise you to avoid this product. ... show more

  • Loving This Ring!
Size: 8 Style: Black
This smart ring is amazing! It looks stylish and lightweight, so it feels more like jewelry than a fitness tracker. It accurately tracks my heart rate, sleep, steps, and even blood pressure — all without the bulk of a watch. I compared the data with my Samsung Galaxy Watch, and the readings are practically identical, which makes me trust it even more. ... show more

  • Great Alternative to Bulky Smartwatches
Size: 9 Style: Black
I was pleasantly surprised by how sleek and lightweight this smart ring is! The ultra-thin design makes it very comfortable to wear all day and even at night—I hardly notice it’s on my finger. The sleep tracking has been accurate, giving me detailed insights into my rest, and I like that it also monitors daily activity like steps and calories. ... show more

  • Watch for Nickel sulfate allergies......in all smart rings !
Size: 9 Style: Gold
I have an allergy to nickel sulfate and after a week of wearing, my finger was inflamed. I would like to suggest to ALL manufacturers of these smart rings to take metal allergies into consideration. I'm on my 3rd manufacturer and so far so good but the week isn't up. 😳 Functions of the ring worked very well while I was able to wear it. ... show more

  • Thin and comfortable.
Size: 8 Style: Black
Great tracker for my mom. It tracks her heart rate, sleep patterns, steps and more. It's thin and not bulky as some other rings, that makes it more comfortable to wear. The quality is outstanding. The color is great and doesn't seem as it will chip at one point. The battery lasts a couple of days without having to recharge it. Easy to setup and not confusing at all. ... show more

  • It meets my needs.
Size: 9 Style: Black
I never know a ring could do so much work. I use it to monitor my steps and sleep mainly. It does the work. I need to press on app to read heart rate and blood oxygen. The battery lasts one day and recharge fast. It does not last long, but what can we expect for a tiny ring with tiny battery? It's good enough for me, anyway. ... show more
