You can buy a rechargeable e-ring with several sensors and even a tiny screen for like 20$ on AliExpress. 75$ for a non-rechargeable, e-waste ring with just a button and a mic is insane.
Point is to not having to take it off at all, as next thing is going out without it and losing that convenience. Though I guess they can also invent a finger-mounted powerbank for it; I remember buying a case with an embedded powerbank for one of my earlier Android phones...
Sure, but I don't think that ditching the combo O2 blood & heartbeat sensor, charging chip and the screen, and adding instead a mic is worth a 55$ upcharge.
Yeah, this is an embarrassing product to create. We don't need more e-waste, and most people are not shipping this back to the company (i.e. if they continue existing and recycling the devices).
