I mean, I get it. But I don't think they do anything that "phone in hand discreetly tilted near chest/stomach" doesn't do. If anything this has a recording light, and I can use both my hands :P Essentially a miniature goPro strapped to my eyes.

Honestly at this point if I am in public I just assume someone (or something - cctv's everywhere) is recording me at all times.
