I owned one of these as a child.
They were battery operated, portable record players with motors that fluttered the audio like crazy and the needle wasn't diamond or even sapphire. But a STEEL needle that actually DUG into the 45 RPM record you were playing. My mom listened to it and asked "Why does this thing sound so bad?" and she opened it and saw the shavings the needle had done to the grooves.
Needless to say, she quickly upgraded me to a REAL record player.
