Customers say

Customers find the Oura Ring’s sleep and activity tracking features impressive, with accurate monitoring of heart rate and sleep patterns, and consider it better than an Apple Watch. The battery life and functionality receive mixed reviews – while some report it lasts days and works well, others say it doesn’t last and stops working after a week. The sizing kit helps avoid guessing the wrong size, though customers note the sizes are not traditional ring sizes. Moreover, the ring’s scratch resistance is concerning, with customers reporting it scratches too easily. Value for money opinions are divided, with some finding it worth the money while others say it’s not worth the price.
