This product has shocked the nation since its debut a few years back. The violent movement and loud screams have startled and amazed! This is a high energy centerpiece. Unit is supplied with a fog machine, par can light, powerful strobe light, tape player, high volume amp and speaker, tape of screaming and electrical sounds, motor with gear reducer, rigging, metal base and wooden chair. Awesome! Not for the timid. Should be mounted to the floor.
