## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Just what I needed
  

*by G***N on Reviewed in the United States on October 4, 2022*

Good quality product. Reason for low rating on installation was because the ends had to be removed in order to snake it through the hull. Opening in the center console was to tight to pull through. Since the original cable that is permanently attached to the charger has fuse holders already installed. Cut the extension just behind the ones there. After running the cable installed terminal ends using water proof splice. Works as advertised.
