I liked it a lot. I compared it with the Garmin and it seems to be quite accurate in measurements. The app is also very good. For the price, as a first ring, it's worth it. I chose this one over the 10 because this one has a temperature meter. Based on the reviews, it seems better. As for the size, my suggestion is to type the size you wear and the size you want to buy in the GPT chat, it will analyze and give you the size. In my case, size 25 in Brazil, size 11 of the Colmi R09 was perfect.
Well packaged and works on the iPhone
I received it within the expected time, the color and size are just right... I am satisfied with the product. The only defect is that the battery only lasts 2 days, which might be due to the settings I used. But otherwise... it's beautiful, and from what I've identified so far, the sleep monitoring is very accurate.
Apparently, the setup was easy and I liked the appearance; it even comes with a silicone case for protection against scratches. now testing
I loved the ring. I compared the metrics with my Apple Watch and everything matched perfectly. Regarding the size, I will share my experience to help those who are purchasing the ring: according to Colmi's data, my ring should be size 11. But I did a lot of research and saw that it wouldn't be the right thing to do. My finger measures 55mm in circumference and 15/16mm in diameter. (Aro 15/16 from Brazil). So I decided to take size 7. The size was perfect (a little loose). So be careful with the size, measure your finger carefully and, if possible, measure the size of a ring that fits well on your finger, in order to buy the exact size.
Article very well packaged, of excellent quality, with Portuguese language support and super easy to install. I recommend it.
The O-ring fit perfectly on my finger, everything works perfectly. The delivery was super fast.
The ring is simply perfect. I bought it a bit hesitant, not knowing if it would arrive, but it arrived perfectly. It's original, comes with its protective cover, which is a little rubber thing, the ring charger, and the case, which is a cute thing. It measures very well what it promises: sleep, heart rate, SpO2, and sports, among others. I'm loving it. My measurement was spot on; as I saw it was bigger than a normal ring, I ordered the size 8 instead of the 9, and it fit perfectly on my index finger.
Very very fast shipping! Ordered it on a monday and it arrived on friday of the same week! Great packaging and comes with accessories, app is also easy to install and use. So far so good, would recommend!
The ring is beautiful and functional, but getting the right size is a struggle.
Excellent
It’s a great ring, the app interface is good it just don’t get you an overview.
Apparently the battery lasts a long time, it's a bit big for me if you're wondering, it's the same size as the Samsung 13. The truth is it's quite comfortable, it was just my mistake regarding the size.
Very nice ring and works as described. Only thing is don't follow the size chart to buy the size, follow the standard sizing sytem. I am 6.5cm so i got size 8 and not size 11!! Be careful.
Well this is my second one , i hope i can give it a better rating in months to come . I had one already was so happy with it , got it last october but by december it wouldn’t bind with app . I tried them all switch off phone unbind and try again , i fully charged it but nothing . I really hope am lucky with this one . Come back to me in like 4/5 months and i’ll do another review . Hi i got my volmi r09 in feb but it’s already collapsing . not working properly . i charged for three solid hours , i tried unbinding it and connect again after but nothing . it works for an hour or two and then that’s it . i’m really disappointed .
Very nice and well-made, but the size didn't fit. According to the measurement instructions in the ad, the size should be 13! I ordered a 12 and it still was too big. But I requested a return. Let's see if I can get a refund after they receive it back.
The size did not match the measurements and I bought a size smaller. The very kind seller allowed me to return the item and purchase the correct size.
The truth is that it works well at the moment. The size corresponds to what was shown. I will buy again if everything goes well. Friendly and fast seller.
The ring is excellent and delivers what it promises; I recommend buying a size smaller than your actual measurement. It comes with a protective case for the ring, a finger circumference size gauge, a Type-C charging cable, and a cable for charging directly into the ring.
