I loved this thing back in a day. In a world where cassette players were popular and music was a must, there was one specific reason that killed the vibe of players. Batteries. They were absolutely useless. You would spend your whole day listening to music, so typical life of 2 batteries were about an hour. Not good for a 10 year old with limited money. Carrying big player just to listen to radio while riding your bicycle was a non needed hustle. So this thing come in handy for every day use. It was a size of 3 credit cards.
