The COLMI R09 Smart Ring is a sleek and stylish wearable that combines health monitoring with modern design. Featuring a unique concave design, the R09 is now 20% lighter, making it even more comfortable for all-day wear. This feather-light, durable smart ring provides 24/7 heart rate tracking, body temperature monitoring, sleep monitoring, and activity tracking to help you stay on top of your health.
Crafted with a titanium steel shell and advanced low-temperature potting technology, it offers a 5ATM & IP68 water resistance rating, ensuring wear ability and resilience. The R09 delivers the ideal blend of functionality, fashion, and comfort.
This smart ring does what it says and seems sturdy enough. The app isn't flawless but it gets the job done. For the price, I doubt you can get a better deal. Battery lasts about 4 days which is pretty good considering how small this is.

I purchased this ring to see how much sleep I am getting. I wear a women’s size 7 and the size I ordered is comfortable for me. The ring charged quickly. I was able to download and pair it with the phone app easily. So far so good. It also records my steps and heart rate.
