## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality as expected from them
*by H***S on November 8, 2025*

Great construction and they work

### ⭐⭐⭐⭐⭐ Great Value
*by T***Y on May 13, 2026*

Great Value

### ⭐⭐⭐⭐⭐ Nice junction for powered items.
*by T***M on August 17, 2016*

Used to create a junction block at my waste tank for when I remove the sending unit (instead of hard wired) this makes removal much faster and easier. Make sure you order the right size (amp, or screw size). Most of the complaints are because somebody ordered a 10 screw size for number 8 connectors (won't work). Sure there are better items but this works for its intended purpose and have no issues.
