  • Impressive for the price!
Size: 9 Style: A-Silver
I’m honestly shocked by this product. I’ve worn this ring for going on 6 weeks now. I originally purchased after having some spikes in my heart rate I wanted to monitor. I wanted to try out a cheaper option of the pricy, name brand before I committed to spending a chunk of change. I am pleasantly surprised by the quality of not only the ring, but the app. I love the sleep tracking function and the ability to access stored data unlike my Apple Watch. The ring is comfortable and fits well. The sizing guide is tricky. It’s so hard to measure millimeters with a flimsy string as suggested. I did order two different sizes and went with a smaller size than what I originally measured. Overall, I’m shocked this product costs less than $30 with no monthly subscription. I’ve influenced just about every family member and coworker to purchase this ring. ... show more

  • Terrible Battery Life
Does not hold a charge well. Battery only lasts one day when fully charged. I like the vibration alerts but not worth it when you constantly have to charge. I will be returning.

  • Loses Bluetooth connection
Size: 9 Style: A-Silver
I've worn it for 2 days and every day I have to re-pair because it loses Bluetooth connection and then all my step data is lost.

  • Control your health
I bought this smart ring to monitor my daily activities and improve my health. I loved it because it's comfortable and lightweight; it doesn't feel bulky. The battery lasts for several days and charges quickly. The design is elegant, and I like that it measures steps, sleep, and heart rate. It's also waterproof. ... show more

  • Just read me before you buy
Size: 9 Style: A-Silver
I loved the idea of it being able change music, swipe videos and tracking what I did. Sad part was I lost this ring in a week. I had problem before I started. The screen was too sensitive whenever after I washed my hands. My music would turn on and off randomly cause my other fingers would touch the sensing part. So at the end I had to wash my hand without the ring (that’s how lost it). Second I exercised and checked my heart rate on the ring, it was showing me low heart rate. Than I put my hand on the treadmill sensor and my heart rate was high. At that time I didn’t trust the ring for heart rate anymore. The AI also didn’t work… I tried tapping or doing something it just never worked. ... show more
