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. 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. Our included switch tops can be removed and replaced with the color of your choice: Red, Blue, Yellow, or Green. It is all up to you.
