[This review was collected as part of a promotion.] Horrible, worked fine for a month and then it stopped working and they won’t replace it. They said it’s not possible to replace. Do not buy!

[This review was collected as part of a promotion.] Good purchase. I use it all other times except when working out. Can’t use the ring when lifting weights. Color is fading a bit. But I love my ring.

Got the ring as a birthday present 3 months ago and have been really happy with the insights it's given me and how it motivates me to have healthier lifestyle

[This review was collected as part of a promotion.] I am very satisfied. Comfortable to wear and I get very good feedback. Had it for almost 3 months and very happy with it

Have had it for about 2-3 months and it has been surprisingly accurate at tracking my sleep and cycle. Provides very insightful information on temperature and HR. Is very comfortable. Battery lasts a decent amount of time.
