    I was using the Apple Watch but lets be real, there only so much it can tell me. Enter the Oura ring. Especially as a woman to be able to track cycles, amongst many other biomarkers this has been the missing piece for me to help gauge my health and know when to push hard or really let myself rest. So far it's just gotten better as I continue to use it and build up the data.

    Have only had it a few days. It was a Christmas present. I traded for the color "cloud" (white). It looks nice and isn't too heavy which was my concern. You have to wear it 5 days for all the "things" to show up. I'm excited to see all of the cool things.

    Three weeks in, and I’m obsessed with my ring. The blue ceramic looks amazing—way more polished for work events than my sports watch ever did. Every feature I’ve used so far has been great. Buying at the Brookfield location was super easy, and the staff member who helped me knew exactly what they were talking about.

    I’ve had my Oura ring for over a month now, and I absolutely love every it. It keeps me aligned with my goals, and if you like to see numbers, then this is for you. The only downside is I do a lot of sauna and heated workouts. There have been a few times where oura has been miscalculated the amount of calories burned (too low) or not capturing the work out entirely. For this reason, I did get an Apple Watch to fill the gap. But other than this, oura is superior in every other feature.
