## Customer Reviews

### ⭐⭐⭐⭐⭐ i would recommended
*by J***Y on October 19, 2022*

easy to installed and so far have no issue with it.

### ⭐ Appears the post bolt was damaged.
*by R***R on April 6, 2024*

The nut threaded on the other post by hand, so it wasn't the nut. So I put a socket on it and the post came loose, broken. Their are no access holes to thread the wires in or out. So I don't know how to keep it waterproof when you drill holes in it. Not that I cared. Appeared by the instructions that it mattered which post was connected to the engine battery or the auxiliary battery. No way to tell which was which by the diagram.

### ⭐⭐⭐⭐ Works as intended
*by L***S on January 19, 2024*

The hardware included is not adequate. Included 2 wood screws. Instead of bolts to secure the back lid to make it water resistant and to mount to the desired location. I had to find my own mount hardware.
