I like that it has an auto-off function, which saves power when not needed; plus there's no need to mess with any buttons or controls if you want your projector off for long periods of time such as during sleep mode (elevation). The screen flickers occasionally while using this feature but does so less often than some other projectors we've used previously -- perhaps because our room was relatively small compared to others where they tend be larger? Definitely recommend considering these features! We are able use them without having someone around who can adjust settings/controls - great convenience!!
