I bought this smart ring just 3 days ago, but it is a very good item.
the dedicated app is user free friendly , the design of the ring is fine and the battery have a long duration.

The size perfectly matches the suggested size according to the measurements. The color is more yellow than golden but still is cute. It has double texture and I think it will prevent scratches from being seen

Ordered size 8. for Ukrainian 18. I quickly downloaded the application and connected quickly too. As a gift, they put the cases on the ring, it's nice, but I thought that I would have to buy. Charges perfectly through the charging box. Not yet tried to use. I will then add feedback

Quality excellent price. Very precise on cardiac and vascular activity. On the sleep to be reviewed, but at this price it deserves five stars.

I arrived before the date and in excellent condition

Functionality
I've been using this ring for about 4 days now and the conclusion I can draw is that for it's price range, it's really good, the app is user friendly too.
I've bought it mainly for sleep tracking and I'd say that it gets it about 80% right, it does have a tendency to think you're sleeping whenever you're just lying in bed, it's counted my insomniac evenings and my my easy mornings scrolling on my phone in bed as "light sleep". But to it's credit, it never thought I was sleeping when I was out of bed.

Look and fit
One thing I'm really disappointment with is that it isn't actually gold, it's Rose gold. This may not matter to some, but I strongly dislike rose gold and it clashes with all my gold jewelry, I've shown an actual gold colored ring in the picture and you can see the difference. I'm also not al all a fan of the glitter band, but this was the only ring that came in my size, it would be great if Colmi would make their future products in smaller sizes as well!

Snygg design och bra functionalittet på Denna smartaring.
Geräven bra information angående hälsotillstånd.

Amazing for your price. Good precision in the accounting of steps. Good accuracy in the measurement of heartbeat. For the price you can not order much more.

it fits, is fast and most important the app works good, in English / Dutch.

Beautiful, comfortable and functional

Cool gadget shows interesting data including sleep readings. Pretty informative

So far, the ring meets 100% and is great price quality.

Very satisfied with the quality of the ring. Beautiful and sound quality. The Charger also looks good. Touch!

Ring works very well, it was sent the day itself and got it within 6 days. You can see your steps accurately on the app, sleep, heart rate, HRV, blood oxygen. I use the ring for the steps and sleep and it works perfectly. Also easy to connect with mobile phone via Bluetooth.

Shipping was fast, function is good and size is perfect (size 13). Use it daily and have no issues with it, shower and/or handwashing doesn’t affect it.
