Sounds great, delivers little.
I have been using it for a couple of months and found it to be underwhelming. The claims are grand, but the reality is different. You can't put your face in the middle of a screen, but the top of your head is always cut off. Any movement of your face results in your entire torso with clothes and all moving along with it. It's because you can't properly define your face. There is only one option, a rectangle to define your face.
To get any reaction at all you need to be really close to the camera, otherwise it will simply freeze.
If you use the "microphone only" option, the head hardly reacts and you can't really see any speech patterns emerge.
There is zero support. You get promises, but have only one option: pay. It's ok as a gimmick at low level, but too expensive to actually enjoy it.
Not impressed right now. Lot's of potential.
