I tried them at a promo event. They had to be sized for your head/eyes, so the demo glasses had to be held in a particular way to see the screen. They were alright. The frames were reminiscent of big hipster frames, which I don't like, but they weren't outrageous. The visible area was small and neat, but I couldn't see any use for it. Probably the size of an apple watch, just floating in the corner of your right eye. The demo was walking directions and talking to alexa. They didn't sell because they weren't very useful and were very expensive. Maybe Google's current strategy is the correct one - keep developing the tech for well-scoped, very niche applications until some day the tech might be good enough for general purpose applications. I think that day is still far away.
