I loved my Oura Ring 3, but one day it just stopped working, and it was past the warranty period so that I couldn't get a replacement. I thought it was stiff to pay _another_ $300 for a new ring.

At first, I thought I could try to fix it myself. But I found that the repairability scores for the Oura Ring are atrocious.

Even looking at Pebble's new voice ring, it's designed to be thrown away when the battery runs out. I like the idea of smart rings, but they seem wasteful and products not really built to last.
