I suggesting triggering input on a watch, not voice recording on the ring. In my suggestion the ring would be a ‘dumb’ input device.

If someone said “that’s years ago” I’d assume 5+. If someone said “it’ll be years before that’s released” I would again assume 5+.
To be two I would expect “that’ll be out in a couple of years”, or “in a year or two”.
For this ring I would write “battery life is between 12-15 hours of use, which will typically last about two years under normal use”
Battery would last for decades just as a button.
Happy to answer any questions you have!

I imagine the reason is reliability, but USD$99 plus international shipping every two years isn’t worth that to me, sorry.
Aside: I loved my kickstarter pebble and my steel, btw!
