these so call portable projector be all crap . do not expect to watch movie or anything . I think this stuff should be $ 100 . it be simply a toy that make you frustrate after 3 month . if it be $ 100 , I will pay otherwise it be not worth the money . however , if you want expensive toy go ahead buy , or if you have money to waste . but , I would bet you will feel the same . it be worth $ 100 !
