The data matches their CPAP, and the sleep features seem to be extremely accurate. It's a good tool for tracking health and activity, and tracks steps, heartbeat, oxygen saturation, and shows how much deep and light sleep they get.

Great competitor to popular brand smart rings

Great competitor to popular brand smart rings
I did a lot of cross-research to find a smart ring that would be right for me. Out of all the competitors to Oura that I came across, this one had some of the best reviews and was the only one I came across that was able to track basal body temperature. I give 4/5 stars because, after a few weeks, my temperature is still not syncing and giving me accurate information about what my temperature is, exactly, and when. Other than that, the sleep features seem to be extremely accurate. The in depth reports that come out once a week are very insightful as well. It looks great, hasn’t gotten scratched (as I was worried about from other reviews), connects and charges easily, and is super light weight. It’s very comfortable to sleep in. As far as sizing, I normally wear a standard size 6 on the finger I chose to wear this one, and I ended up purchasing a size 8 due to the measurement chart listed in the photos (great reference by the way). So I would get a size or two bigger than you think you need, unless you measure accordingly with the chart.

    Great customer service, very good product for the money

    Reviewed in the United States on December 25, 2024

    Size: 10Color: SilverVerified Purchase

    I bought this ring because I wanted to also buy the smart glasses by Ray-Ban and I justify that much money. My sister spent the same amount of money as I did for both products for just the well known Oura ring. At first I was really disappointed because it wasn't counting any sleep for me but I recharged it and contacted the manufacturer who immediately got in touch with me and gave me the steps. Then it was accurately counting my sleep but it was under counting my steps by 5 to 6,000 compared to my Fitbit so I knew that my Fitbit just couldn't be over counting by that many steps. Again I reached out in the customer service was fabulous and it turns out that after a day or so it appears to be much more accurate and counting my steps. It is also extremely comfortable to wear and seems to have an incredible battery life so for the amount of money I spent on this I couldn't be happier and I hope it continues to work as well as it has been because it's much more comfortable and easy to wear than a Fitbit.

    Great battery life, charge once a week on Sundays for 2 hours. Easily worn and never gets in the way and comfortable. No issues syncing data and seems acurate- it's our first time of such a device. Sleep data matches my CPAP except if I'm up early and just chilling on the couch before work, then it records as light sleep. Heartrate is accurate as well as o2 levels as measured against another device. We are 60 and have started regular exercise again and it seems accurate for steps while doing that. Questionable for daily totals of steps as days I work from home, it's generous IMO. Highly recommend the sizing kit before buying, which we did and had no surprises on that front. I would highly recommend as a lower cost unit and first try at it's use.

    Gold wears off quickly…

    Reviewed in the United States on January 15, 2025

    Verified Purchase

    I don’t typically leave reviews, but I felt so bummed out about this product. I got this item when it was on sale for $99. I was looking for an affordable alternative to the Aura Ring. I am on week 2 of wearing this ring, and the gold is already incredibly worn. I live a very normal lifestyle and am not hard on my hands. It lasted almost 12 days and then suddenly it’s wearing off at a quick rate. It works ok overall. I find the step counter to be inaccurate, but the rest of the features are good. The app is nicely designed and easy to use. For $99, I would expect the finish to last a lot longer. Disappointed.

    I have my ring for 1 month and I like it a lot. So far it has functioned as expected. The information compared to my Apple Watch and machines I use that calculate distance calorie and heart rate seem to be spot on. The sleep monitor and stress monitor are a great help. It allows me to manage my stress and it literally confirms what already know.

    Important missing feature, price is erratic

    Reviewed in the United States on October 18, 2024

    Size: 10Color: SilverVerified Purchase

    Update: It still lights up and syncs, but no data on the app. Basically useless after 3 months. Also, if you are going to buy…watch the pricing, it seems to change A LOT!

    This ring was a disappointment from the start because it does NOT track blood pressure which I needed. The size is off, I lost one and the other slips off a lot. Due to numerous issues with the order I ended up with a free one, but those issues were Amazon. That being said, it is comfortable to wear. The measurements seem to be relatively accurate. It's a good tool for tracking your health/activity. The battery life is great, but you'll want to remind yourself to charge it.
