Genial
I’m really impressed with this smart health ring! It looks sleek and stylish, and it’s so comfortable that I often forget I’m wearing it. The health tracking features are very accurate — heart rate, blood oxygen, sleep, and even blood pressure monitoring work flawlessly. The companion app is user-friendly and gives me a clear overview of my daily health and fitness data. Battery life is also excellent, lasting several days on a single charge. Overall, this is a fantastic device that combines modern design with powerful health tracking. Highly recommend it!

A Very Good Value!
Size: 13#
Style: Silver
I have an Oura ring for comparison but my trial period ran out so I renewed for another month while I evaluated this alternative. I have the 2.0 model in this ring, silver color, size 13 (big man hands). First week I've found it very good, exceeding expectations so far. The activity tracking (steps) is pretty accurate to my Oura ring and Apple Watch, within 10% at the end of the day. This is an acceptable variance because all devices track things a little differently. Heart rate and blood O2 seem spot-on accurate. Blood pressure is nice, but I can't tell how accurate it is because I do not think my Oura ring has that function. Sleep tracking is good, however it seems to reset at midnight and count hours from there until wake-up time. I am usually in bed a couple hours before midnight so I think I'm missing some sleep data due to the hours asleep before midnight. This might be a setting that I need to uncover and figure out. App is much more simple than Oura. Less fluff. I think Oura might have a couple more features than this ring (like cycle tracking for women) but I don't need that at all. Oura's app is more complex, I like this app much better. Battery life so far is good. about 4 days between charges, but it charges fast so pop it in the charger when you get a shower and you should never need to worry about running out of battery. Fit and finish is excellent, it seems durable and very difficult to scratch. Also very comfortable on the hand. It is a touch narrower than the Oura ring, and the outer diameter is just about exactly the same. In the attached photos, the Oura is the black ring and the 2.0 is the silver one. You can see how the 2.0 is a bit narrower thank the Oura which I like.

My new Ring!
I’ve been using the Smart Health Ring 2.0, and I love it! Although it fits a bit loosely on my larger fingers, it’s super comfortable, and I wear it every day even during Pilates class. The sleek design is scratch and fingerprint-resistant, and it accurately monitors my heart rate, blood oxygen, and blood pressure. Plus, it’s waterproof, which is great for daily activities. It syncs perfectly with both iOS and Android devices. Overall, the Smart Health Ring 2.0 is a fantastic choice for anyone wanting to track their health. And looks fashion! Mine is Rose gold.

Would have recommended until I took the ring off
Size: 9#
Style: Rose Gold
I’ve only had the smart ring for 4 days now. I took the ring off to recharge and this is what my finger looks like. I will be returning, loved how everything measured and seeing my data but the discoloration has caused me to pause and return. This is my experience only so purchase with care.
