  • Super high tech for a low price
Size: 10 Color: Black
I really like this smart ring. It is small and comfortable to wear all day and night. It tracks my steps, heart rate, blood pressure, and oxygen level very well. The sleep tracker helps me see how well I rest at night. I like that it is waterproof, so I don’t have to take it off when washing hands or in the rain. The battery lasts a long time and charges fast. It works great with my phone, and I don’t need to pay for any subscription. Very happy with this ring! ... show more

  • So far, so good.
Size: 8 Color: Pink
Just got this smart ring and so far, so good. It tracks my heart rate and sleep which is what I mainly wanted. The blood pressure and oxygen readings are there. It's waterproof and works fine with my phone. No subscription is a big plus. For the price, it's a solid basic tracker.

  • Very good health sleep monitoring device with least maintenance.
Size: 9 Color: Black
It fits the finger so well. Easy to take out for recharging and the battery lasted 4 days, after first charge. I tried monitoring heart beat, blood pressure, steps, most importantly sleep. It's very interesting to see my deep sleep, light sleep, awake hours during sleep. It became addictive the first week and helping to refine my sleeping habits. Love the ring so far, good investment. Device/packaging itself is of high quality. ... show more

I’ve been using this smart ring for a few days and I’m impressed. It tracks my heart rate, sleep, and steps pretty accurately, no monthly fees, which is great

  • Not worth it. The app used to access the ring is designed badly and requires invasive permissions.
Size: 8 Color: Pink
Requires a badly designed app that requires too many permissions. The app requires permission to read messages, access contacts etc. Poor instructions, hard to figure out how to sync the ring to the app. I'll be returning this

  • I’m pleased with my Smart Ring
Size: 9 Color: Black
Purchased my Smart Ring, and OMG I’m loving it. It keeps track of my sleep patterns, my blood pressure measurements is accurate, how many steps I’m taking in a day, etc. It does exactly what the description says. I was a little confused at first linking the ring to the app on my phone, but it was me. So far I give this ring 2 thumbs up 👍🏾 👍🏾 ... show more
