Now for the glasses, the assembly was easy. When I sat up then, I could tell a slight pressure on the nose, this takes a short time the joy of VR experience. Likewise, you can still see the right and left the area, which completely takes away the VR illusion. Comfort is not the case, you will be so constantly reminded that you have those glasses on.
Now for VR use, I use the HTC One M8, so first downloaded a VR app turned on and plugged into the VR goggles. First, the key lock has been activated once, so smartphone out again, keylock and deactivated again purely, then appeared the additional users of the HTC strips on because the screen is touched while net Slide in many places, so again. Frustration factor rose and rose. When it finally went off, but a lens was totally out of focus, the other not. Was probably bent the bendable foam, bit the bracket, no success, lens remained blurred. The VR app ran about 3 minutes, during which I had increased the urge sell the glasses, because I feel as uncomfortable.
Conclusion: It can be viewed with the glasses VR Apps, but the comfort plays a much bigger role.
