This isn't a question I understand, but I appreciate you writing it. At the end of the day it's up to you - if you think this is useful, please use it. If you don't want to use it because of the 4.7 grams of e-waste, I do get it.

All consumer tech is intentionally disposable. That's life. Especially for tiny smart rings that are water resistant. It's a ring, it's going to get banged up, you'll lose it or smash it. It's new tech - there will always be a new version, etc.

Better to have loved and lost than to have never loved at all.
