The "user's eyes visible to others" part has been widely panned, even by the most enthusiastic reviews. There are two major problems with it.
One, it's not the actual user's eyes, it's just a bad rendition of some eyes - without any of the extremely subtle facial expressions that happen with the skin around the eyes, and without any amount of certainty from the other that they are correctly reflecting exactly what you're looking at. We are extremely good at noticing exactly which direction another human is looking in, and when theire gaze shifts, so even minor inaccuracies or lag are jarring.
Much worse, the screen they used is so bad that the eyes are barely visible in almost any amount of lighting.
Either way, even if this "solution" actually worked, the visor still covers far too much of the face to be able to get a normal expression.
