I have a different memory than you regarding the expected lifespan of the ring, which I think was 1-2 years with normal usage. I don't plan to get one, but it certainly hasn't soured me on the brand. There's pretty clear tradeoffs involved with putting replaceable or rechargeable batteries in such a small device.
Some people were very upset that iPhones didn't have replaceable batteries like Blackberries. But it would seem that pretty much everyone got over that. With even tinier devices like AirPods and smart rings, it would seem like even less of an e-waste issue. I say this as someone who has no plans to get one of these things, FWIW.
I'm not tilting at the "the battery cannot be removed!" windmill. This is a whole new low. It's consumable consumer electronics.
The only thing that will prevent this from becoming a cautionary tale for the ages, a Juicero of e-waste, is its lack of cultural relevance.
It's like the argument about reusable grocery bags: they can have a smaller carbon footprint than disposable ones, but only if you use them like 120 times (most people don't come close).
How big would the charger be, how much bigger would the ring be, and how many charge cycles would it have to undergo in order for the e-waste math to be favorable? And does that solve the issue, or will people still be complaining that it's not a replaceable battery?
I guess I just tend to give a little more benefit of the doubt to the creator, who has presumably thought about these things and at any rate is making a niche product that is physically very small. It seems like this could only reach a reasonable volume of waste if it were mass-market or much larger per-unit.
I just don't think we should make stuff like this, and I definitely don't want to signal support for it on my wrist.
