Perfect Fit From Sizing Kit

[This review was collected as part of a promotion.] The sizing kit worked well for me to size the ring. Once I got the ring, the size was a perfect fit.

Sizing kit made my purchase simple

[This review was collected as part of a promotion.] This was easy to order, size myself and book my ring. Size 8 works like a charm foe me, and now giving this to mom to try as well, as I want to buy her this ring for Christmas.

Great fitness tracker device on the finger!

[This review was collected as part of a promotion.] I bought this product a few months ago and have really loved it. What I especially appreciate is the sleep score and the way it provides personalized suggestions to improve sleep and recovery. The stress tracking and insights are equally helpful.
