The Go Talk button allows you to record a 10 second message (in any language). The replay button is large, which is great for people with mobility problems, such as cerebral palsy. Our 8 year old loves it, because he just has to slam his hand down on the button in order to ask for a drink when we're feeding him.
It's small size is also handy because it's easy to add to any number of spots, without being intrusive. The Go Talk button comes with a built in magnet, which makes it easy to attach to a fridge or other metal surface. The button battery is included, so it's ready to go as soon as you receive it.
All you need to do is press the record button on the back (a red light comes on to let you know it's recording), and then press the large play button on the front. It's so easy to use that you can quickly change the message several times a day to meet your changing circumstances. Consider having several Go Talk buttons placed in key spots to get the most use out of them in your environment.
