Best health device!
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The best to track sleep, heart rate and any health. Way more accurate than any of the other health tracking devices. Love how long it could go without charging for days.

Oura Ring
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought the size 10, was a bit tight so I returned to the store the next day to get a size 11. this purchase was early in December and the salesman at the store indicated that I had till January 15th to return if the size was not right. Unfortunately when I returned next day, the gentleman working the service desk would not exchange the ring unless I paid $100 dollar difference (ring was on sale for either Black Friday or Cyber Monday and the guy said he could not exchange at the sale price. So I returned the ring, got a refund, and then purchased a size 11 ring from another company. SO, I really enjoy the ring, but unfortunately for Best Buy I had to buy it elsewhere.

Great health monitoring technology
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Very happy with the whole process. Was able to size the ring appropriately for me in the store, and since then I've loved having this insight into my health, especially sleep quality and when my body is fighting some bug. I think the device and app provides a lot more features for women then men, such as cycle tracking, but overall happy.

Oura Ring Review
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Oura Ring feels effortless — light, simple, and easy to forget you’re even wearing it. It quietly tracks your sleep, stress, and daily rhythm without any screens or noise, just clean insights that actually help you understand your body better. The battery lasts almost a week, the app is clear and friendly, and the whole experience feels more like a wellness companion than a gadget.

Pretty neat
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The ring is super cool doesn’t seem to track burned calories accurately. But it does track sleep well. I've had a whoop before & I would say it tracks sleep slightly better. Only downside is it’s not really great at tracking lifts, & forms of workouts.
