Customers say
Customers find the ring to be a powerful tool for health and wellness tracking, particularly appreciating its comprehensive sleep and readiness scores, and consider it better than an Apple Watch. Moreover, the ring is comfortable to wear, with one customer noting it feels like they’re not wearing it at all. However, the sizing and battery life receive mixed feedback – while some find it perfect, others note the sizes don’t match standard ring sizing, and while some report 6-day battery life, others mention it only lasts a few days. Functionality and value for money also get mixed reviews, with some finding it well worth the price while others say it’s not worth the cost tag.
