when I got my Cinemizer plus I realized very quickly (after the first anger had passed over pixel errors) found that at very contrasting passages in movies, the image showed a red a blue ghost of bright parts outwards and inwards. This occurred on both the iPhone 3GS as on the 3G and the PS3 as with all possible settings. so I decided to turn on the support of Zeiss and there I was instructed to send the glasses to exchange. I just got the glasses back (kindly now lacks the USB cable) with the note "This device is working properly and do not know to the specified error image." So if the device, which I have here exactly works as it should, then I have every advise to buy these glasses. Note: I do not wear glasses and have both eyes 0 diopter deviation.
