What’s the value proposition here? Free no-questions-asked replacement if it breaks? Free upgrades when new models come out (though they have no real incentive to keep developing new “forever mice”)?

If my mice on average last, say, 6 years and cost $175 (I splurged on a high-end one last time), the subscription will have to be less than $2.40/month, and since customers absolute hate subscriptions, especially if there’s no real benefit, probably even less than $1.50/month for most to even consider it.

In fact the Logitech mouse before my current mouse lasted 12 years and cost me $75, so that’s a max subscription cost of 50 cents/month for it to be comparable.
