This is the one-ups-manship that the free market creates. This combines Oculus, Google Glasses, and shutter glasses.
I’m not sure about the claim of no motion sickness. I think that is likely true in the AR mode. When one changes over to the full VR lenses I would think they have the same problem as Oculus.
Also, I can’t really tell what resolution the glasses are providing.
