These projectors have be tested to make sure that everything works. All of the ports are tested to make sure they function properly, and the device has been restored to factory settings. These projectors come with a power cable and remote. The remote may need new batteries. All bulbs are used with the hours listed in the variation. For a bulb with more than 5000 hours, the projector will flash a warning message saying that the bulb should be replaced soon.

Note about bulb hours: Although these projectors are rated to get about 5000 on the bulb, that amount is not guaranteed. I've seen bulbs last much longer, and some blow out at as low as 2000 hours. Keep this in mind when purchasing these or any projector with a used bulb. Please contact us if you have any questions, concerns, or curiosities.
