GoTalk Button records a 10-second message, and the large "play" button insures easy use. Its compact size (about 2" diameter, 5.1cm) makes it easy to slip into your pocket, or use the built-in magnet to display on the fridge or any metal surface. Record lock feature eliminates accidental erasure. Place several Buttons around the classroom or your home for multi-messages. This is a great augmentative tool for children to utilize between home, school, and activities.
