Love this ring!
I’m honestly impressed with the Colmi Smart Ring R02. It’s lightweight, comfortable, and looks like a normal ring—not a piece of tech. I wear it all day and night without even noticing it.The health and sleep tracking work great, the app is easy to use, and the battery lasts several days, which is a huge plus. Charging is quick and painless.For the price, this ring is an absolute steal. If you want health tracking without wearing a bulky smartwatch, this is totally worth it. Highly recommend!

Awesome smart ring for a good price!
Been using it for a few days and it holds charge pretty well! I’ve only had to charge it once so far. I love the sleep tracking aspect of it and the ease of the app. Rings fits good! I got a size 11 and it fits on my thumb perfectly. Connects well to my iPhone. Definitely recommend!!

Smart, Stylish, and Subscription-Free—Just Watch Out for Metal Allergies!
I’ve been wearing the COLMI R02 Smart Ring for a bit now, and honestly, it does everything it’s supposed to. Heart rate? Check. Blood oxygen? Check. Sleep tracking? Check. Sports tracking? Yep. And it all comes in this really pretty rose gold design that actually looks like jewelry, which is a huge win for me.Full honesty moment: if you’re sensitive to fake jewelry, this might not be your jam—I learned that the hard way. Totally my fault for not thinking it through! But besides that, everything else is perfect. I also love that there’s no subscription needed, unlike other smart rings, so you get all the features right out of the box.All in all, it’s stylish, functional, and really easy to use. Just make sure your fingers can handle the bling!

Best product ever!
I’ve been wearing this smart ring for a few days now, and I honestly didn’t expect to like it this much.It’s very lightweight, comfortable, and it doesn’t feel like a tech device at all, it actually looks like a fancy ring.What I like the most is how simple it is. It tracks my sleep, heart rate, daily activity, and stress levels without me having to check a screen all the time. I just wear it and forget about it.The battery lasts several days, which is a huge plus, and it’s perfect if you don’t like wearing a smartwatch 24/7. I also love that it goes with everything; casual or dressed up.If you’re into wellness but prefer something discreet and minimal, this is a really good option.Size 7

Smart ring
So far I have been using it for a few weeks. I like a lot of the features and the battery last a long time. The only thing that I don’t like is that , it doesn’t track my naps. I took a very long nap while wearing the ring and it didn’t track it. The app is so easy to use and the ring has been comfy. I sized upTemperature tracking would be a good plus!I think it’s worth it if you don’t have a smart watch and if you want to keep track of your steps/ sleep.Waterproof ✅Comfortable ✅Battery life ✅

Sleek Design and a FREE AP
Very sleek design and not bulky. You need to make sure of sizing as the smart rings do run differently. I like that it tracks my sleep and has a FREE Ap. For the price point it’s a great ring.

The sizing was wrong and it takes forever to get to you even with prime and takes forever to get your refund
