Great for college
||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The ring is gorgeous, as a college student the Oura ring is great for tracking stress and keeping track of my sleep schedule. I have a tendency to stay awake until 3 AM getting work done, ever since I got the ring it reminds me that its bed time.

Nice Smart Ring
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.My smart ring fits my finger perfectly. I was concerned about washing my hands with it on but it is waterproof so it is not damaged. I've also worn it in the shower and it still works perfectly!! I do wish it had more 3rd party apps I could use with the data it collects. Overall I'm happy with my purchase.

Best health tracker
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Best health tracker I've ever had. I have the Samsung watch which is not as accurate. I tried a Hume band and it was not right for me. It did take some getting used to on my finger but it's amazing. Excited for all of the data to come through!

Love it! Great purchase.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.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.

Love it!
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.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.

Health Game Changer
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.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.

I'm Obsessed.
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.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.
