## Customer Reviews

### ⭐⭐⭐⭐⭐ You can find anything on amazon !
*by J***  on September 15, 2025*

Worked like a charm

### ⭐⭐⭐⭐⭐ Great Replacement Power Adapter for Casio AD-1 / Casiotone MT-30
*by J***K on April 10, 2019*

I needed a power supply for a Casiotone MT-30, which uses a Casio AD-1 power adapter. While the MT-30 is not listed in the description, this cord fits perfectly and works flawlessly. I tried using a "universal" power adapter I had lying around the house. However, even when 7.5V was selected, the universal adapter would produce a buzzing noise from the speaker. With this cord there is no buzzing noise, it sounds just like it's running off the batteries. Great cord, exactly as pictured.

### ⭐⭐⭐⭐⭐ Works with casio keyboard
*by D***N on June 13, 2024*

Quick shipping, and works for our older casio keyboard
