Best Smart Ring
|Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.[Employee of bestbuy] I tried 3 different smart rings, and this is the only one I didn’t return. I was a bit worried about another subscription, but the insights on the app are worth paying for, if what you’re looking for is the ability to understand your body more. A bit annoying to work out with if you tend to grip weights hard. Might have to size up if your hands tend to swell throughout the day.

Recommend
||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Good ring and seems pretty accurate. I put a cover over it and it does make it bigger but keeps it protected. Battery last about 5 days and charges in under two hours. I would recommend this product.

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 4
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.First smart device I have been able to sleep comfortably wearing every night. I run my everyday health according to my Oura. It’s so convenient to only charge it every 7 or 8 days. Give it a 10+

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.
