Great Smart Ring for the Price
I’ve been using the COLMI R02 Smart Ring for a few days now and I’m genuinely impressed, especially considering its price point. It’s lightweight, comfortable, and tracks my heart rate, sleep, and steps surprisingly accurately. The battery lasts several days on a single charge, and I love that it’s waterproof so I don’t have to take it off all the time. If you want a stylish and affordable way to track your fitness, this is a great buy!

Easy to connect and use
I absolutely love this smart ring. The fit is wonderful. The ring is beautiful. It was easy to connect to my phone and very easy to use. All the features are great. I can’t wait to use this ring and help me improve my sleep quality. This would be a great stocking stuffer for Christmas.

Budget Smart Ring
For $50 I wasn’t expecting much but have been pleasantly surprised. The app is easy to use and very similar to its name brand more expensive counterpart.

There must be a better device.
I wanted to like this ring. I bought the size that would fit over my right hand knuckle(right hand dominant) so that was a good fit. The fully charged battery lasted maybe 36 hours. That didn’t bother me. BUT reading my pulse at 99 while sitting reasonable still for an hour caused me to check my pulse elsewhere. It was 70 bpm by taking pulse and using my phone app.It did best at sleep tracking but I was paying more attention to the data while awake so that accuracy wasn’t what I needed most. I know what time I go to bed and when I waken. I had no issues connecting to the phone .I’ll keep trying.

Convenient, reliable, and arrived fast!
I’m really impressed with this product! The convenient charging makes it easy to keep powered up, and the sleep tracking is surprisingly accurate — I love seeing my nightly insights. Shipping was super fast, and it arrived in perfect condition. Definitely worth 5 stars!

Discolored my fingers!
I bought this to wear at night so I could track my sleep without wearing my smartwatch 24/7. I wasn’t very happy when the finish started rubbing off the very first time I wore it. It’s been 3 wears, and this morning my fingers that were touching the ring are discolored! The worst part is the discoloration is not coming off! Most of the finish seems to have come off as well… I’m assuming that’s what’s all over my fingers.Although the ring seems to work well, I cannot under any circumstances recommend this.

Simply AMAZING
AMAZING RING! The ring is so lightweight but still durable. The app is easy to navigate and I love that it syncs with the Apple health app. I also enjoy that it tracks overtime and puts it into a graph that is easy to read. I got the size 9 and can easily fit it on my index and middle finger.

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 ✅
