The ring works very well, the app integrates with Apple's Health app, and I compared it with my Trex watch, and the markers are very good! It's the same ring sold by Halo, which costs 4 times less.

Works perfectly. great product, much better that wearing a watch.

Pleasantly surprised that this device is almost as good as apple watch 6 that i have. since apple doesn’t want to replace battery and asks us to buy a new watch every time, decided to try this r09 smart ring after seeing many people buying this and giving good reviews. i tried a fitness band recently but it didn’t work well as it was giving too many steps even though i walked less. this r09 smart rings is able to measure steps, hr, spo2, hrv & stress at regular intervals and the data more or less agrees with apple watch. sleep measurement is also as good as apple watch 👍🏼 hope the battery life last long. overall, a good buy and recommended.

Very good, it works and measures everything very well. Just order one size larger so it fits properly.

I am very impressed with this smartring. the delivery was very quick to new zealand. the ring is great quality and very easy setup with the qring software. the accuracy of the results so far match my apple watch ultra 👍 i hope that the longer term durability will match the quality found so far 🤞😊

I was surprised; I'm still using it and so far it's working perfectly.

I've only been using it for a short time, but everything is fine, it measured my sleep... now time will tell if it will last.

I loved it, easy to pair, seems good, size 7 for the index finger, left hand

I loved it, everything went perfectly!

I loved the quality but it was a bit too big for me, I will buy another one!

I've only been wearing the ring for a day and I'm super happy with the purchase. The app works great and is easy to use. 10/10

I loved it! It does everything that expensive ones do and looks great!

Delivered super fast. set up was easy to do. size is perfect. so far very accurate. app is the same as the halo ring.

I really liked the ring, and for the price, I think it fulfills its function. Heart rate and sleep monitoring seem reliable, but the step counting was a bit off in my opinion. I haven't tested the sports monitoring yet. I ordered size 07 and it fit perfectly on my finger; I measured according to the product's size chart.

I received it in 6 days, it charges well and the app works well too.
However, I ordered size 10, but when I measured it with a string, it was about 6.6cm.
If you put it on a tight index finger, the knuckle will hurt over time, and if you put it on a slightly loose ring finger, the middle finger joint will feel uncomfortable due to the interference of the ring thickness.
I put on the ring that I hadn't worn before, and it feels quite different, so I'll have to try wearing it here and there to get used to it. It's quite thick.

It works perfectly.

I've been using it for a few weeks now. works great, app that goes with it is easy to use. you can shower with it, it didn't loose color by now. battery lasts for a few days

Excellent product, works very well and syncs with Apple's health app. The only issue is the size; I bought size 8 and it only fit my little finger. I need to buy another one in a larger size.

Very good

Received quickly. surprised with how good the quality is. size is perfect, guessed based on others in reviews with pictures. charged quickly, app is easy to install and use. so far would recommend.

I recently bought the gold one in size 7, but I feel much more comfortable with size 8, so please order one size up from your usual size because with summer coming, your fingers will swell, and I assure you that I was not comfortable at all with the size 7! It's really great. It accurately calculates my sleep, stress, etc.! The app is excellent. Order it with your eyes closed 😘

I am not at all disappointed with the ring. Honestly, I didn't expect such precision, the QRing app is amazing! Everything is perfect. Whether it's my steps, stress levels, cycle tracking, or even my heart rate, which are completely accurate because I have my Apple Watch and it's exactly the same. Go for it, it's clearly the discounted version of an ouaring. I chose size 7 because I generally wear that size for my rings that I put on my ring finger, but I advise you to go one size up because my finger personally swells up when it's hot, when I do sports, and also when I sleep, so I would have been much more comfortable with size 8, but size 7 is perfect when my fingers are normal. I ordered size 8 in silver and I can't wait to receive it. Don't hesitate for a second to take it. It's a very good purchase.
