  • So good! Looks great and works perfectly.
Color: Gold Size: 9#
I'm so happy with this smart ring! First off, the gold color is gorgeous—it just looks like a nice piece of jewelry. The best part is that people actually compliment me on my ring and don't even realize it's a smart device! It’s super easy to deal with, especially when it comes to charging. It just charges up quickly and without any fuss. For tracking, it does everything I need. I love that I can check my sleep, count my walking steps, and monitor my heart rate and blood oxygen. It gives me all the important info I need without having to wear a chunky watch. That's the final huge win for me: it's not heavy like a watch at all. It's so light and comfortable; I barely notice I have it on. If you want a cool, discreet way to track your health, definitely get this ring! ... show more

  • It monitors heart rate, sleep, and blood oxygen levels. Very convenient.
Color: Gold Size: 10#
I bought a size 10, but I've gained weight recently and can only wear it on my ring finger. My child saw it and said, "Where can you find such a big idiot? Don't miss out!" It cracked me up. But I have to say, the ring's functions are really great; it monitors sleep, heart rate, and blood oxygen, it's comfortable to wear, and it's very affordable. The sizing issue was just my fault; the product itself is really useful. It charges quickly and lasts for 5 days; the app displays the battery level. My heart rate is a bit fast, and I used to use a blood pressure monitor to check it, but this ring is so convenient. ... show more

  • Worth your $!
Accurate pedometer and heart rate monitors. Loved the color as well as the thoroughness of the sleep tracking (duration of each sleep phase is differentiated which is super cool). Quick to charge and to set up/bind with your phone on the app.

  • Excellent fitness tracker!
the ring is an excellent fitness and health tracker! It accurately monitors steps, sleep, heart rate, and blood oxygen, and the application syncs easily with both Androids and iPhone. I love that there is no subscription fee and its waterproof, so I can wear it anywhere. It is also lightweight, comfortable and stylish. ... show more

  • You get what you pay for here
Color: Black Size: 11#
Unfortunately the cost verifies the product. Very inexpensive compared to other rings, but it doesn't track my sleep (shows about 45 mins to 1 hr 20 minutes of sleep per night, not deep sleep either) steps are consistently off from anywhere between 2-3k compared to my Samsung watch..was hoping i could replace my watch with the ring.When doing activities, but with how inaccurate it is, it makes it basically unusable unfortunately. Bought 2, for the wife and I, inhave Samsung, she has Apple, and both rings are similar compared to our watches If you don't have a smartwatch, you might think this is pretty accurate ... show more

  • Almost perfect
Color: Sliver Size: 12#
I really liked the ring, it fit nice, looked great not bulky, it tracked steps, heart rate, O2 very nicely, However I have sleep issues and this was the feature I was most interested in, it did not fare well in this area, most days I didn't sleep at all according to the ring. I hope they can fix this portion ... show more
