GRN has produced a range of specialized hand wind audio playback devices for use in areas where electricity and batteries are expensive or difficult to obtain.
Since the early days we've made hand wind record players, and the amazing CardTalk cardboard record player.
We graduated to the Messenger and TapeTalk hand-crank cassette players.
And until recently we produced the hand wind Saber MP3 player.
