NEC LT150z Portable Presentation Projector. Very reliable projector and is easy to travel with on airplanes.Has a good projection range from 3.9 feet to 21.8 feet. I’ve projected further with it but you start loosing some color from your presentation.It sets up quickly and easily.It has been tested recently and works well.No batteries included for the remotes. The NEC remote uses two AA and the Logitech uses two AAA.
