I mainly use it to monitor my heart rate and sleep patterns, and it’s been amazing to see how my body responds to daily activities.

So far so good only arrived this morning so not had it on long enough yet to understand or test out the full range of what this ring can do. I love the fit & the colour I chose (gold), glad I opted for that one now & not black.
I just received it and started using it now. So far it feels good. I was a little bit worried if that ring might not fit my fingers, but it's fine, it fits well. I'm really looking forward to keep using it and the results!
I was a little disappointed that they did not have the rose gold, but the ring fits well. The app was easy to install and set up and so far I’m very satisfied, especially for the price.
