### ⭐⭐⭐⭐⭐ How it works
*by S***Y on August 18, 2020*

The switch was very easy to hook up and worked great starting my generator from inside my camp

### ⭐⭐⭐⭐⭐ Easy to install
*by J***N on May 27, 2020*

### ⭐⭐⭐⭐ Works great
*by G***. on June 30, 2020*

The switch was easy to install. I would like a bit more grip between my console and the switch because the body of the switch can turn inside the console. I will add my own gasket to fix.
