buy this think that the remote controlled powerpoint slide show . the projector arrive before the estimate delivery date -- which be when I realize it do not have that feature . if you do not need that feature -lrb- I 'll accept blame for not research it better ! -rrb- , this seem to be a pretty well make -lrb- albeit basic -rrb- projector . I call they customer service for info -- the person I talk to be very helpful and knowlegable . I be impressed . I return the unit and purchase a different one , again , on Amazon .
