I am very satisfied with this product. This is the second one I buy from Colmi. Perfect, beautiful, my wife loved it. It works perfectly and the app records sleep data, calories, heart, blood oxygen, etc. very well. Battery for 4 days, plus the case allows you to recharge up to 5x at least and is very compact. Delivery before the expected deadline. Excellent packaging with manual and accessories.

Delivery was super fast! Work great and connects with the app. I’m still checking the data to see if it’s accurate but for the price who cares. Charges well as well

Fits and works great

A rare find and the app is really similar to Lora Ring, I really liked it!

Honestly, this ring is quite nice, I must say. It makes a small impression and the design is cool. However, I admit that it lacks a bit of finesse in the details. For the price, it's still a great deal, no doubt about that. I recommend it if you're looking for something not too expensive and pretty.

Satisfied. Easy installation of the app and connections. For sizing get yourself a sizing kit from amazon for oura ring and go from there. My size 11 fits perfect. I will post further review after a mont of usage for so far for looks and build quality, very very nice. In addition, extremely fast shipping.

Arrived and working. This is the third device.

What a beautiful ring. The app looks good too. I had an Ultrahuman air, but it didn't last more than 10 months. I'm very curious about the quality of this ring, so far very satisfied.

Item as described works well, great.

Very good ! Uses for a coupe of says , easy to set up and the sizing is correct

Choose size 8 fits well. . Could of probably go a size 9 for my index finger when the hot summer comes. Qr code available on the manual. Very easy to set up. Easy to go through the app. This my 2nd smart ring this one has more features which is why i purchased this ring. Wished it had gps tracking. Great price. Highly recommended.

Looks good and works fine.

This is the third ring I've bought, this one is for a gift. The Colmi brand is very good and the sizes fit correctly as indicated. The app works great and the charge, with daily use, lasts up to 7-8 days. Very good ring.

The price-performance ratio is very good. I've had the ring for 4 days now. It measures steps and heart rate just like my previous more expensive smartwatch. In my opinion, this Colmi R10 ring measures accurately. I'm very satisfied. It also came with 3 different silicone covers. Practical when wearing it at work so that the ring doesn't get scratched. Great.

Quality item, I recommend this seller 5*****

Excellent product

Very good but i should have went a size up. This is usually my size, but there is a slight discrepancy here. Accurate tracking, good feel of the material, very lightweight. Has its own charging case, very useful and compact. Would recommend. 👍🏻

Excellent, actually super fantastic.

Love this ring. I compared the ring to a garmin watch. The ring is more accurate. Depending on the settings, i charged it once in three days; charges very quickly. I'm very happy with the ring. Going to buy one for my husband

Quick fast delivery and great quality

What a great little device., slip it,on your finger and now you know your internals…. Easy to,set i-, easy to,o-erase.

Cool ring, really liked it. Measures everything perfectly and helps monitor health.

Great

Used it for about a few months now and i fkn love it. It tracks my steps , sleep sometimes it doesn’t track naps through out the day but that’s okay it’s very accurate with sleep and steps

It arrived perfectly, well-packaged and on the correct date. It comes with a size chart inside the package that says my finger should be size 8, which is equivalent to size 17 in Brazil. I ordered size 9 (without knowing) and it fits well, not tight at all, making it comfortable to wear.

Great!

My second colmi r10. Great looking ring and i like the grainy texture of the ring. I now have silver and a black one. Works well, decent battery life and great app.

Nice product, i got one before and i bought this one for my friend

Very nice. Very hope it good

I use it everyday, great battery life

Fits well ... Surface durable ... Measurement values appear plausible ... everything okay!

I like it.

It works well and the battery lasts long, but the stride isn't correct. The app is very intuitive.

Difficult to chooze the right size otherwise very good quality ring. Looks of a high quality as pictured

So far so good. Finally a quality product on aliexpress. Usually products on ali are literal trash. But this ring works well!

The ring monitors perfectly, and it also connects with Apple Health.

It tracks sleep well. It doesn't use much battery - it used 35% in 3.5 days and is now at 65%. I was able to accurately determine the size using paper and pencil.

I took the measurements they recommended before ordering it and it turned out to be large, but I only use it for sleeping with a bit of tape so it touches the skin. I just wanted it to monitor sleep, and I was pleasantly surprised; very good. I have a smartwatch but nothing compared to the ring, the ring is much more precise. Good purchase. Be careful with the size.

Nice rings, good for monitoring

Great service, very happy with the product

I am satisfied with the performance, but the size is too large. Choosing two sizes smaller than the measured size will provide the perfect fit.

Usually a size 11 but size 9 fits my ring finger well. App works great, charged for a couple hours & am on day 3 no charge. Love it

Excellent. Works really well.

Everything is okay.

Second time buying rings from this brand! It has excellent accuracy (both sleep and steps) compared to my Samsung Watch 6 and offers a wonderful cost-benefit ratio! But the Gold one is not very durable, the first one after a year is already silver and quite scratched, but I am a HARD user! So I pull to charge! Ah, it depends on how many things you activate and frequency; the battery lasts for 2 days! Synchronizes only with Google Fit! Yes, it's great, and asking to be with Samsung is too much!

Top Function

Here's a 50-word review for the colmi smart ring: Absolutely loving my colmi smart ring! It’s incredibly lightweight and comfortable, i barely notice i'm wearing it. The sleep tracking is surprisingly accurate, giving me actionable insights into my rest. Battery life is solid, lasting several days. It's a sleek, subtle way to keep tabs on my health without a bulky smartwatch. Highly recommend this convenient tech!

Pleasantly surprised with the quality of the smart ring and it's capabilities and battery life

Perfect
