I dunno, they are/were demoing them at Universal Orlando and plenty of people were checking them out. Price tag probably scared most away (who's dumping 100+ on glasses at a theme park?).
I'd buy a pair if they were more like traditional action cam style glasses. The technical limitations right now make them far too expensive for what they are.
You'd be surprised: when I worked in retail, I was told that the sunglass stands in the theme parks were 3 of the the top five grossing stores at the time for the luxury sunglass brand that I was working for. Admittedly, this was...almost 20ish years ago, but, I'd still think this would be true today.
