Smart Rings for Men Women Advanced Health Fitness Tracker Monitor Sleep Heart Rate Oximetry Activity Waterproof Compatible with iOS&Android White 8# (No Subscription Required)

Bought mid July. Fitness tracker didn't really work, but heart rate/o2/blood pressure was pretty close. Difference was consistent, so easy to adjust for.My main issue is that it fell apart. The inside completely separated from the outside.I'd like to exchange, but past return window and I can't figure out how to contact seller.

I am very satisfied with this ring. I primarily bought it to track my sleep time (I can't stand wearing a watch while sleeping), and it performs exceptionally well in that regard. Additionally, I've found myself using many of the other features regularly. Overall, I highly recommend this ring as the perfect complement to a smartwatch.I've been wearing this ring for about a week now, and I really like it! It's incredibly comfortable, to the point where I hardly notice it's there. As someone who often suffers from insomnia, being able to track my sleep with data is very gratifying. I also appreciate the reminder features, which help me maintain a regular routine.

At first, I was skeptical about wearing a smart ring, especially considering all the mixed reviews. However, after using it, I found it very convenient and stylish while providing comprehensive insights. Here are a few key points I want to highlight:1. If you don't plan to use all the features this ring offers, it might not be worth the investment. For me, heart rate monitoring and sleep tracking are essential. The ring tracks my sleep quality and duration, providing detailed reports every morning, helping me adjust my daily habits for better rest.2. I've always found smartwatches bulky, especially when paired with formal or fashionable outfits. The manufacturer claims the outer ring is made of ceramic and the inner ring of stainless steel, making it comfortable and very beautiful. I love this texture! Another very important reason is that I don't like wearing a watch while sleeping, so the ring is more suitable and convenient. It doesn't affect the function of tracking my fitness and health statistics.3. The test results are quick, showing my blood pressure and heart rate in about 10-15 seconds, which is excellent. When my stress levels are high, it reminds me and suggests relaxation techniques. I also like the blood oxygen and blood pressure monitoring features.4. It's worth mentioning that this ring has an NFC function but is only applicable for access card scanning. I haven't used this feature because I don't need it where I live.Lastly, remember two things: 1) Make sure to get the correct size. Fortunately, size 8 fits my index finger, so I recommend purchasing a sizing kit or checking their website for more information. 2) The app is great and very detailed. I spent some time watching tutorial videos and reading the manual, which was very helpful. It's not difficult to use, just has a lot of features.
