Record any single message directly into the BIGmack communicator and press its activation surface for playback up to two minutes in length. Connect a toy or appliance for additional motivation. The toy or appliance will play for the length of the recorded message. See our video for more information. With its large, 5 inch activation surface, BIGmack is an excellent choice for persons with visual impairments and persons with physical disabilities who require a larger target area.
