I be very excite about this item for two reason , its portability , and the fact that the bulb would last a very long time so I would not have to worry about replace it as I travel internationally . unfortunately the projector start malfunction right off the bat . within three month I have to replace the cord , it cost sixty two dollar . after I receive the cord , within a month the new cord do not work correctly . I do not think there be anything wrong with the cord , it appear that at the junction point of the cord go into the projector be a malfunction in the design , as it do not want to sit straight for very long , cause it to not connect correctly , which cause the projection to cease in midstream . ca not watch thing very long before this happen . also , within six month the pixel I think , the screen start show one white dot , then after another month it be three , and after a year it be like sixteen white dot on the screen from the lens coat fall apart or something . bottom line , within one year this thing be a piece of junk , and at four hundred dollar , it s a big disappointment .
