It's cool, but the fov is narrow, and the area of visible pixels changes significantly with the position and orientation of the device relative to your eyes. Re

It's cool, but the fov is narrow, and the area of visible pixels changes significantly with the position and orientation of the device relative to your eyes. Reach up and slide it a little bit up or down on your nose and you gain/lose enough area that you can spend minutes adjusting knobs and fittings to find something that seems usefully minimal. It's not particularly comfortable in general. And, as a wireless standalone unit compared to a desktop computer, it renders relatively very low quality 3d graphics because of the need for high framerate stereoscopic output and the typical constraints of a several-years-ago smartphone.
