Gave me peace of mind when it came to sleep data
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Used Fitbit for many years but while dealing with nervous system regulation the fixation on amount of sleep became paramount. With the Oura it gave me more confidence that the data is more accurate (though REM could be off) overall and for Deep. This is minus any gold standard testing which is not accessible for me now. There is a lot of data in the annual membership and I have determined it so far has been useful but it's also good not to focus on all the data. Had to downsize actually within the return window because the larger size was comfortable but it also fell of my finger and when placed on other fingers not all the sides were touching my finger. Would suggest getting a Best Buy plan to expand return window to 60 days if you're unsure.

Perfect
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I absolutely love my Aura Ring! It’s super cute, sleek, and comfortable to wear every day. I was honestly surprised by how many benefits it has — I love being able to see my sleep patterns, activity levels, stress, and overall wellness all in one place. The data is easy to understand and really helps me stay more mindful of my health.

Better sleep data
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Purchased this to get better sleep data. So far I feel more confident that this ring is capturing more accurate data than another tracker I had used for years. Love the smooth ceramic coating and the sleek design.

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.

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.

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!
||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.

Oura Ring
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I love my Oura ring. I upgraded to a generation 3 to a 4. I gave my other generation 3 to my friend who has been wanting one and she loves it. I bought a generation 4 for my boyfriend and best friend for Christmas and they are equally in love with their ring.
