Unfortunately I had vision problems, subjectively rating

To this end, I have to say that unfortunately I can not say so much about the functionality of this device, therefore this review is not to be regarded as universally valid or directly on the technical details and the playful / application-rich scope. I had bad problems could adjust myself to the 3D optics and could not therefore play a long with it. I personally had that have then caused me headaches severe vision problems. Initially, I thought I have to get used to it but only after a few days and no improvement, the device went on the way back. I can at this point not even say who has problems with the eyes should not buy this. I think it depends on the person himself to it and whether it can adapt to the 3D graphics or not.
