The screen resolution is very close to the Oculus Rift DK1, Moto G 2nd's 720 x 1280 and the DK1's 1280×800, and it looks the same, the problem is that the magnet does not seem to work for me, I have this:

and it seems to work well, lenses seem nice, image is clear, but there is no room for glasses at all, and I wear glasses because I am nearsighted, however the image can be made to focus without my glasses by adjusting the lenses, but the lenses are very close to your eyes, and the unit is very small, also the area around the bridge of the nose will start to hurt so you may need some extra padding or modifications, this unit does not have a magnet slide thing, but I have lots of magnets, and I was under the impression that I could just move a magnet near the phone and that would work, but I ether get no effect or the screen turns off, the magnetic sensor seems to be near the power switch on the Moto G 2nd.
The gyro is so jittery it makes games unplayable, and thats a shame, the demos seem to play fine and work full speed.
I am very likely to stick to watching videos with this unit, if I can fix the nose problem, -but- because the screen is divided into half or less the video is low quality but watchable.
