I buy this projector while I be station in Baghdad in the spring of 2006 to play my ps2 game . I purchase it refurbish at 100 hour and 3300 hour later , it be still work like a charm . sometimes I forget to clean the dust from the filter but that do not affect the play any . I mainly use it as a second monitor for my laptop through hdmus and at the time of my purchase , it be ahead of it be technology for price ratio . it be one of the best investment I have make and go great with a bottom scissor Da-Lite projector screen . 3 thumb up !
