### ⭐⭐⭐⭐⭐ Works great
*by V***R on September 22, 2025*

Great fit

### ⭐ NOT 9V negative center as claimed
*by E***E on November 3, 2025*

NOT 9V negative center as described. The listing says -9V center, the label on the bag says -9V center... But my METER says it is +9V center and none of my pedals will function with this thing. Useless. Buy the SEEHOM version of this converter, it works correctly with -9V on the center. https://www.amazon.com/dp/B0DD77LYG5
