Customers are saying
Customers have good things to say about the product's overall performance, with many finding its sleep tracking phenomenal and its comfort super comfortable. They also appreciate its long-lasting battery life, appealing ceramic design, and accurate data. While some users noted that the size took a little adjusting to and that there is a slight weight on the fingers, these observations do not detract significantly from the positive experience.

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.

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.

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.

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.

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.

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.

Obsessed!
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been wanting one for quite some time and with the arrival of the 5 discounting the 4, I took advantage and purchased. It’s only been a few weeks so far but I love it. I got an 11 at first and had to exchange for a 10 - the customer service was wonderful as well.
