    Product look and feel is quite attractive. This can be used as an ornament ONLY. Nothing smart in the ring.

    1. Ring gets auto disconnected frequently. No notification for us if it happens.
    2. Do not track like vital signs.. No update on adverse situations like increased heart beats etc
    3. Battery life is less than 36hours and not 4days as marketed.

    Not an easy to use product with extremely poor performance. I don’t see any value for money barring the look of the ring which is worth of less than 1k..Highly recommended NOT to buy..

    Good things first

    1. Unique device
    2. Comfortable to wear
    3. Tracks the stats well, specially sleep but the readings are higher than most of the other devices.

    Areas of improvement

    1. Keeps disconnecting from the phone and it is extremelyyyyyyyyy difficult to connect back.
    2. Battery is not the best. Top is 3 days and it falls at less than 20%.
    3. The cardio fitness doesnt sync with Apple health.

    Biggest Drawback

    1. The Bluetooth tech is not the best. It conks off often, has sync issues and the Apple widgets don’t update automatically.

    My opinion

    At this price, it can be avoided unless the issues are fixed.

    The smart ring is better than a smartwatch because it's small and comfortable to wear 24/7. It's easy to use, and the battery lasts a long time, so you don't have to worry about it dying during the day. I think the smart ring is a great choice for anyone who wants a stylish and convenient way to stay connected.

    5.0 out of 5 stars Paying a premium to track health metrics with minimal effort
    Reviewed in the United States on 11 July 2024
    Colour: Bionic GoldSize: 9 UKVerified Purchase
    I have bought and worn fitbits, watches, and all sorts of cheap health trackers, but never got the habit to stick. So when my wife wanted to track her heart rate after a health scare, I went down the rabbit hole of HR trackers that would be suitable. I ended up getting her a fitbit, but made this purchase for myself, and it's good for me, but because I am very lazy and don't like to wear extras on my body.

    If you care about accuracy or precision of heart tracking, I would not recommend this ring. It does not do either well; it gives you a 15 minute range of HR tracking with min/max HR that it recorded. I occasionally see a flashing green light in dark settings when the ring is doing its measurement, but it happens maybe for 10 seconds every few minutes. Additionally, I cannot wear the ring during any workout that requires gripping weights. Rigid rings and barbells just don't get along well. I have to take it off when I go to the gym, which also defeats the purpose of fitness tracking.

    All things considered, I still wear the ring. A full charge lasts 5-6 days, and I really like the sleep tracking. I find it mostly accurate for wake times, but the REM tracking is probably not %100 accurate. If it were for all the reasons above, I'd give the ring 4 stars. But I've had the ring for 3 months, and I somehow cracked the ring despite barely wearing it during exercise. Upon contacting the customer service and showing the evidence, they quickly sent me another ring. I could not ask for better customer support. Unless their policy changes or they start focusing on subscriptions, I would not hesitate to recommend this product to anyone who remotely cares about their sleep quality and general daily well-being, but nothing too hardcore or specific.

    I love this ring. The app that comes with it provides detailed insights into wellness and fitness. It is also free, as in no subscription. I have used other fitness trackers, and this one goes above and beyond them all. I especially like Ultrahuman's attention to the importance of light in our lives and how it impacts sleep. In addition their suggestions about when using stimulants like caffeine can be beneficial, and when they won't is useful. There's lots of info about improving cardio fitness and sleep. The app is practical, easy to navigate and backed up by science. Thank you!
