Customers say
Customers praise the ring's build quality, noting it performs better than the Apple Watch, and appreciate its sleep tracking capabilities, particularly its heart rate monitoring and comprehensive sleep and readiness scores. The ring's appearance receives positive feedback, with one customer highlighting its elevated look for a wellness tracker. Battery life and functionality receive mixed reviews - while some say it charges for days and works well, others report it doesn't last and stops working. Customers disagree on whether the ring is worth the money. The ring's scratch resistance is a concern, with customers noting it scratches too easily.
