  • Easy to use and looks great
Size: 8 Style: Black
This smart ring works really well with my iPhone and was easy to set up. It tracks heart rate, sleep, steps, and blood pressure accurately. No subscription needed, which I love. It’s lightweight, comfortable, and looks like a regular ring. Battery life is good too. Great choice if you want a simple, stylish fitness tracker. ... show more

  • App doesn't work in the usa

DO NOT BUY THIS RING THE APP DOESN'T WORK IN USA EVERY TIME IM TRY TO LONG IN SHOWS "PROBLEMS WITH THE NETWORK" NOT WORTH IT. Oh and the app consumes phone battery like crazy

  • Good electric ring
Size: 10 Style: Black
I was surprised at how comfortable this ring is. It is super light and I often forget I am wearing it. The sleep tracking has been accurate compared to my smartwatch, and I really like seeing my heart rate without having to wear something bulky. Battery life is solid and I only need to charge it every few days. Overall, a sleek and practical ring that does what it promises. ... show more

  • Crappy app reliability but seems to be a good product
Size: 9 Style: Black
Love the ring it holds a charge for 3+days and the box holds a charge like head phones. But after about two weeks the app went down when I deleted to re download like suggested the app is off the Google app store. Will return if not fixed or reached out to and will go with a different brand! Returned very disappointed that such a good ring uses such a scammy overseas app ... show more

  • Charging but no led on the ring itself.
Size: 10 Style: Black
The ring started out working fine but after a few days it's not working properly. There is no led showing and it doesn't hold charge for very long. It measures sleep patterns but does not link with my current cpap machine. I am able to get some use out of it though.

  • 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

  • Short battery life
Size: 9 Style: Black
I charged the ring fully about 7 pm and went to bed, the battery ran out before I even woke up at 6am

  • Fake Tracking, Wrong Steps, Waste of Money!
Size: 8 Style: Black
This ring is honestly useless. The step counter shows random numbers — sometimes it says I walked 5,000 steps when I was just sitting all day, and other times it barely counts anything even after walking for hours. The heart rate is just as bad and changes every few seconds for no reason. The app barely connects, the charger is flimsy, and the battery dies super fast. I really regret buying this. Looks nice in pictures, but it doesn’t do what it says at all. Total waste of money. ... show more
