Purchased 5-6 years ago. The previous owner may have applied too much voltage, as it's broken and the sound quality is poor. Only 8 of these were manufactured in Japan. I kept it intending to repair it, but never had the chance, so I'm listing it now. It does produce sound and the LEDs flash, but I recommend getting it repaired. No claims and no returns accepted. ↓ For reference: https://youtu.be/aTK-V3CnwUw?si=Dcy6m80_3sT3OPBd
