Nice ring. As a jewelry and gadget
Verified Buyer –
The second ring i’ve bought from colmi and genuinely it’s worth the money. The readings are as accurate as they can be (when compared to smartwatch readings) and the display is bright and clear. It’s very responsive which means occasional accidental activation but it’s not a problem, really. If you’re in the market for an affordable smart device that’s sleek, inconspicuous and does the bare minimum for health monitoring, then this is a good choice. The app it works through also has even more inf…

She’s perfect! I wanted to test the usefulness of a connected ring before investing €300 in a Samsung connected ring, and it’s a success. It’s even possible that in the end, I’ll keep this one! The advantage is that it’s not expensive, less than 30€, waterproof, with a screen (well in the end I think it’s a gadget since I also wear a smartwatch lol). I chose the gold color and the watch is very light (feeling like plastic rather than metal). I think I should have stuck with the silver color, but…

I really liked it, first day and night of use, and so far it’s working perfectly. I’m impressed, it was worth it, very satisfied.
Verified Buyer –
Excellent value. Unobtrusive monitoring of steps, sleep time, pulse and ow level.
Verified Buyer –
Superfast delivery with ring cover extra 😍 , the side button is a game changer, especially reaching the proximity to check the time and functionality. App is pretty easy and quick connect.
The only downside is it gets really hot when charged.

I measured with a paper and ended up buying one size larger (it was 12 and with their tape it was 11), so it became a bit loose.
But the brand is very good (similar to Galaxy Watch), the brand exercises well too (volleyball). Only the steps that mark much more. The battery lasts well too (about 3, 4 days measuring the information every half hour).
Mine got scratched up a bit, but it’s understandable since I’m using it everywhere, including playing volleyball on the sand.

The ring has surprised me for the better. I’ve been wearing it for a few days and it’s great. It even comes with a silicone case for you to cover it when you exercise and lift weights so it doesn’t get scratched. The measurements depend on you wearing it correctly, and knowing that they won’t be like a professional heart rate monitor, the HR and SPO2 measurements are quite accurate. And then the screen feature that suits me perfectly because I don’t wear a watch, so I see the time on the ring sc…

One of the greatest things to have work fine software is easy too use. Not to heavy a good fit.. I wear it 24/7.
Can only recommend this item
Verified Buyer –
Very good quality appearance, doesn’t seem cheap but is affordable compared to branded products. It shows heart rate, steps, battery, and time, which is essentially sufficient.
Verified Buyer –
Just received it. App installed and set up. Everything went quite smoothly. Now waiting to see how it works.
Verified Buyer –
Great Smart Ring with various health monitoring functions. (such as e.g. Heartbeat/Pulse, Blood Oxygen and Sleep Tracker as well as Sports) The connection with the Companion App “QRing” works flawlessly without any issues. The firmware update was carried out automatically and the Bluetooth connection is stable without any disconnections..! The display is rotated 180 degrees. ° adjustable so that the ring can be worn correctly on both hands. All data was reliably collected and transmitted to th…

Great product, fast shipment, easy to setup. Shows battery, steps and hour. Size fits perfectly. I’m very satisfied.
Verified Buyer –
Good construction and finishes, both on the ring and the charging base, very complete and I would say precise or very close to medical devices. The only thing I didn’t like is that the app has a religious option, which doesn’t make sense.
Verified Buyer –
A wonderful ring, the display can be adjusted and turns off by itself, it doesn’t glow all the time. Very easy to adjust.
Verified Buyer –
Exceptional item. After loading and configuring it with the QRing App, simply wear it on a finger where it has good grip. You can read: time, number of steps, heart rate, battery percentage. In the app, data is synced very clearly and simply. You can view the history of heart rate, sleep, movement, blood oxygen, etc. Long-lasting battery. In 2 days still 70%. Waterproof. Numbers quite legible for me even without glasses. Recommended
Verified Buyer –
I really liked the ring and the application seems very comprehensive.
Over time I will check the accuracy of both.
Verified Buyer –
Super, lightweight, you can’t feel it on your finger at all. The seller is exceptional, I got the wrong size but he replaced it without any problem. Express shipping and delivery. I recommend the ring and the seller 100%. Pure pleasure.

Bahut acha experience raha!
Product bilkul waise hi tha jaise description mein diya gaya tha. Quality behtareen hai aur delivery waqt par hui. Seller ne achi packaging ki thi aur koi damage nahi hua. Main zaroor dobara order karunga. Highly recommended seller! 👍

Size bit large
Verified Buyer –
I really liked the product’s quality and, above all, the speed of delivery.
Verified Buyer –
It arrived within the established timeframe.
Unfortunately, the measurement was incorrect and the ring turned out to be bigger.
I couldn’t leave a performance review since I haven’t tried the product.
Verified Buyer –
The ring is discreet but at the same time attracts attention because of the screen. The charging is wireless but with its own base. The size is exact to the measurements (includes one), if you don’t want to have problems, take the measurement of your finger carefully and several times (the diameter changes with temperature). The application is quite complete considering it’s a ring. Personally, the battery lasts two days for me (barely).
Verified Buyer –
I ordered 2 rings for myself and my husband at once. I read a lot of reviews and was hesitant about the size, but decided to take size 11 for my finger diameter 7, and size 13 for my husband, who has a finger diameter of 8. In general, I got the size right because during the day the finger can swell and change size. I like the app; it really allows you to track metrics – sleep (I have a small child, I get up for a nighttime feeding and check in the morning; you can really see when I woke up and …

All is great. It would be wonderful if the ring has a temperature sensor like the previous version r09.
It would be good if the delivery person can just press the bell to let us know item has arrived we found the item at the shoe rack outside the door 1 day later. It could have been taken by other people.

City express delivery. I immediately plugged it in to charge, it showed 98%. The application is simple and clear, I quickly set it up and connected it quickly. Wore it immediately. The first time it discharged very quickly – actually overnight to 30%. This is somewhere around 19 o’clock. The next morning, I put it on charge while getting ready for work – it was charged. Very quickly. I was away all day, it’s already 8 in the evening, and it shows 93% charge. Monitoring of everything possible has…

Recieved two weeks before expected delivery time. I ordered 13 size and putting it on first time it looked i ordered oversize, but now after wearing for few hours, i am happy that i ordered snuggly fitting size. I am very feeling very easy wearing it. All its functions are working like the battery status, steps, time and heart rate. Will its sleep usage tonight. But overall its a good gadget in this price.
Verified Buyer –
Excellent product of good quality and superior to those sold in physical stores in Brazil… I recommend this purchase and the seller and the delivery person… I recommend the purchase.
Verified Buyer –
Nice ring, i love it i bought one size small número 12 and it fits well.
Verified Buyer –
This ring with display is really amazing.
You can see the time, battery level, heart rate, and steps, and it’s quite similar to my Samsung watch. And the sleep was also reasonably accurate. My Samsung ring is broken and I need a temporary replacement until mine is hopefully made. But actually, I find this one much prettier :).
I am very happy with this smart ring top.
Verified Buyer –
Perfect, good sleep tracking, etc… just for the number of steps, I’m not sure if it’s super accurate, complete application with many different sports options.
Verified Buyer –
Well, I bought one size smaller and it fits great. Testing it out, but it seems to work perfectly!
Verified Buyer –
excellent for monitoring sleep
great for checking the time without wearing a watch.
I need just enough
long-lasting battery
precise measurement
Verified Buyer –
Looks and feels very good. Fits well. Reaches 8 days without charging.
Verified Buyer –
Fits perfectly on my finger, the display is very visible.
Now test and get used to it.
Verified Buyer –
Alright, let’s see how long the battery lasts.
And on top of that, Colmi sends you a finger gauge so you don’t make mistakes in future measurements.
Verified Buyer –
It’s light, sturdy, pretty, and I like it. The cost performance is the best.
Verified Buyer –
It’s a great ring. It fits very well on the finger and after some time you get used to the thickness
