## Customer Reviews

### ⭐⭐⭐⭐⭐ Seems fine
*by J***. on March 21, 2025*

Works well, no issues noted

### ⭐⭐⭐⭐⭐ satisfies a need
*by E***. on October 18, 2023*

I use this to extend the microphone for a Williams amplifier

### ⭐⭐ Incorrectly sized rubberized coatings hinder fit
*by A***. on July 18, 2023*

Bought this to extend the cord length on my sewing machine so as to use it on a standing height table. Male end of the cable will not fit into the port on the machine because of the excessive amount of rubberized coating around the head.
