Smart Ring for Men & Women: 24/7 Heart Rate & SpO2 Monitor, 5ATM Waterproof Health Tracker

This is really good well made compared to my jakcom5. Jakcom5 never worked i'm just wearing it. But colmi yes working well very easy to start up. Compared to jakcom5 not charging at all expensive compared to colmi ro6.

Very nice for this price. Size 11 a bit tight. Would you rather order half a size larger?

Fast shipping. Easy setup through ios app. Stylish and durable. Heart rate, oxygen saturation, hrv, sleep, and stress levels monitored, with real-time recording option. Compact charger. Good product

Excellent item, as described. Better than expected, easy to use with good instructions. Great seller, thank you

The size perfectly matches the suggested size according to the measurements. The color is more yellow than golden but still is cute. It has double texture and I think it will prevent scratches from being seen

Perfect. Just as described. Quick shipping to usa.

the product arrived a bit late, the app was installed, the device connected, it's counting steps, I will continue to check.

Love it ! Its accurate says same numbers as my watch

Great

Well packed, delivered earlier than expected. Was kept well informed of progress by the shipper. Early days and have yet to fully discover the benefits this will bring.

Excellent, I had previously bought a Colmi R10 and I must say that they turned out very well. I have used them every day in my daily activities; including showering and even doing laundry, and I haven't had any issues. They charge quickly, the charge lasts approximately 5 to 6 days, they don't disconnect from the phone (I have an iPhone) and they also work wonderfully with Samsung. 100% recommended.

Product is very good once finally received. Took way too long to receive. Extremely disappointed with the process but very happy with product.

I was skeptical at first but this thing is great. You can monitor spo2, heart rate, stress levels (not sure how they monitor that one), sleep and awake times (very accurate surprisingly), and you can even double tap the ring to take photos on your phone using the app.

Good items works as expected only wish it could communicate with other fitness apps such as stepup and mapmyrun or at least share date with gym apps
