These projectors were used in school up until last year, when they were replaced for newer LCD screens. All of them work and have bulbs (condition can be checked upon purchase, # of hours on bulbs varies). I have at least 4 remotes (remotes can be used interchangeably for any of the projectors). Projectors also have mounts (as shown in pics). Some covers (covering connector panel, non-important to function) are missing. Plugs and cables are included.
