## Customer Reviews

### ⭐⭐⭐⭐⭐ Quality!
*by E***S on August 20, 2025*

Worked out great. Blue Sea for the win!

### ⭐⭐⭐⭐⭐ Blue Sea builds nice stuff!
*by A***F on January 20, 2024*

You end up spending a little more for a Blue Sea product but they almost always offer a high quality part you won't have to worry about. This terminal block is made from a better-than-most plastic that doesn't split or crack when fastening it down. The terminal screws hold and don't strip out easily. It's amazing how fast the cost of a wiring project can balloon out of control but using quality parts will provide a safer system than running generic "unknown" parts.

### ⭐⭐⭐⭐⭐ Well made
