## Customer Reviews

### ⭐⭐⭐⭐⭐ SOLID
*by T***. on December 29, 2024*

with this what you see is actualy less than hat you get, when i recieved mine i was surprised, is larger than i pictured, as you turn the knob thru its positions, it is a solid motion and "locks in" its not all wishy washy its a positive "click" into position...... the lugs where the cables are connected are like 3/8" bolts that are solid enough to put a wrench on and tighten properly without breaking...... it also has a cover plate to cover where the cable connections were made,,,,, theres actualy nothing i could say bad about them other than i wish they had been giving them away when i bought mine :)

### ⭐⭐⭐⭐⭐ Big turn on
*by J***N on November 17, 2023*

This was a great add on to my camper. Had an in line fuse I had to keep pulling when not needed, but this is as simple as a turn. Would buy again.

### ⭐⭐⭐⭐⭐ It works
*by B***T on March 21, 2024*
