Revolutionize Your Health with the R09 Smart Ring: Heart Rate, Blood Oxygen & Skin Temperature Monitoring in a Sleek, Waterproof Design

Absolutely love! So easy to get going, the app is easy to navigate. Ring fits perfectly and came fully charged. Super light weight.

I hope this one will last longer then the first one i bought at another store

The size is large, fortunately the ring fits my thumb, however, it works perfectly and is waterproof. I wash my hands and take a shower with it, and there's no problem.

Extremely impressed with this tracker - i have an oura ring and the two are nearly exactly on the same level of results. The app was very easy to install and set up and the interface is very similar to the other app if you’ve used both. Would definitely recommend this! Sizing - i went 1 size up from my usual e.g index finger is a size 8 us so i chose a 9 - it’s a bit loose but it will allow for my fingers to swell during exercise and in the summer. Save yourself $$$ and get this instead of the more expensive options!

Followed the full measurement description but the ring i ordered from the size that was suggested to fit me is way too big, the ring itself is fine feels very light and has a bit of a plastic feel but it looks very accurate to description and i’m sure it works great.
