It's only a week. If it lasts longer than Oura then it’s going to sell.
I’ve bought a few of these already and decided to get this one as a gift for my niece since she works out a lot. It looks nice, feels lightweight, and is easy to wear daily. She liked that it tracks basic things without being bulky like a watch. So far it’s been working well and the battery lasts a decent amount of time. Good option if you want something simple.
Lightweight, accurate, and comfortable. Tracks sleep and activity well, with long battery life and an easy-to-use app.
I loved it
I really liked this ring. It’s comfortable, lightweight, and looks nice it doesn’t even feel like a device.It helps me track my sleep, stress, and daily activity without needing a watch. It’s also waterproof and works well with my phone.
Its health data is more accurate than expected. The daily activity level, resting heart rate, and sleep quality score all allow me to visually see my poor lifestyle habits. Since there is no subscription fee to worry about, I am always happy to open the app to review my progress every day. Now, in order to obtain a higher "sleep score" and a lower "stress index", I consciously start to go to bed earlier and get up earlier.
I’ve been using this smart health ring for a little while now. First of all, the design is beautiful The health tracking features are surprisingly accurate — especially heart rate, sleep patterns, and activity levels.
I love it, it is so cute, its color matches my clothes and it is very easy to configure with my phone and I can monitor my health.
I've had my ring for about a month now. I love it, it's waterproof, lightweight, long battery life, very stable, gives good readings. Best price for this ring and the size was on point.
Parece Manila normal pero con tecnologia avanzada,es comodo de usar y la bateria le dura bastante,se puede monitoriar pasos y otros datos de salud.
This smart ring is a simple and affordable option for tracking basic daily activity. The setup process was easy by scanning the QR code and downloading the app.One thing I really like is the charging case—it lights up green to show it’s charging, which makes it very convenient and easy to understand. The ring itself is lightweight and comfortable to wear throughout the day.It tracks steps, sleep, and heart rate, but the data should be taken as general guidance rather than exact measurements. For the price, it does a good job for everyday use.Overall, it’s a good beginner-friendly smart ring if you’re looking for something simple and functional.
I’m genuinely impressed with the Smart Ring, it packs a surprising amount of functionality into such a compact and comfortable design. From day one, it’s been easy to use and seamlessly fits into my daily routine. The real time sleep and fitness tracking has been one of my favorite features. It provides clear insights into sleep quality, steps, calories, and overall activity, helping me stay more mindful of my health. The continuous monitoring of heart rate and blood pressure throughout the day adds an extra layer of convenience and awareness. Battery life is another big highlight. Getting 3–5 days on a single charge (and even longer with the charging case) means I’m not constantly worrying about recharging, which makes it perfect for everyday use or travel. I also love how durable and versatile it is. The waterproof design gives me confidence to wear it during workouts, daily tasks, or even showering, and it remains comfortable even for extended wear. One of the best parts is that there are no app subscription fees, everything is included, making it a great value compared to other wearables. Overall, the prxxhri Smart Ring delivers reliable performance, useful health insights, and excellent convenience. It’s a great choice for anyone looking to track their fitness and wellness in a simple, hassle-free way.
Esto es increíble Controlo todo lo que necesito saber de mi organismos con solo un anillo, ajusta bien y fácil de instalar
I’m really impressed with this smart ring. It’s lightweight, comfortable, and I barely feel it—even while sleeping. The health tracking (especially sleep and activity) seems accurate and easy to follow in the app. Battery life is solid, which is a big plus. Overall, a great alternative to a smartwatch and definitely worth the price.
I can't believe such a small accessory offers so many benefits. Besides looking beautiful on my hand—and matching my ring and watch perfectly—it also helps me manage my wellness routine. I simply scan the app, and it installs in a flash; it asks for a few basic details, and then I can take full control of my activities. It tracks my sleep, records my workouts when I go walking or cycling (among many other sports), and monitors my heart rate, blood oxygen, blood pressure, HRV, stress levels, and even my menstrual cycle. It’s incredible that something so tiny can do such big things—and as for the price? Don't even worry about it; it's very affordable.
