A BIGmack is a single message communication device. A step-by-step allows you to record messages in segments and then replay them in that same order. The initial activation of the device speaks the first part of the message aloud and then stops. When you activate the device again, it plays the second part. And so on.
Some step-by-steps an added feature that make them even more valuable: different levels. Communicators with this feature allow you to pre-record several sequences and switch to the appropriate level when needed. Easy, flexible, and practical.
