On time and updated me on the statics, loved it!
Perfect for my needs while travelling but also at home. I particularly like how quiet it is.
I am very happy with the results I had with the Wellhue 02Ring,and the assistance I had. It monitors my sleep very well and I am able to get report with the recommended app on my phone. So it is doing what I expected it to do. Only trouble I had was the alarm at times. I might have been that the battery was low while wearing at night. But only happened very occasionally
