@reibeatall I've got one.

1) Too clunky. even for people who wear glasses, they were uncomfortable.

2) Not great for people who wear prescription lenses, which is a big part of the market.

3) Battery life was crap.

5) Because of various limitations, it was basically just a smartwatch strapped to your face.
