I add this as a second projector in we church basement . note that there be no way to adjust the picture size other than to move the projector itself . it do work like advertise , and have a good picture , -lrb- you may need to darken the room if you be go to use it in the daytime -rrb- and even have built-in speaker . I try it first , and then opt to run plain 50 foot stereo cable with rca type plug , not video cable , and the picture be still very good . the direction booklet that come with it be 99 % useless . -lrb- example : when use the remoter . -rrb- the shipper could not locate my house , even though we have have hundred , if not thousand of delivery use the same address . the seller find out what the holdup be on the delivery , and be very helpful . all in all , I would buy another one or recommend this to anyone else - with the note above .
