## Customer Reviews

### ⭐⭐⭐⭐⭐ Works very well.
*by B***B on January 4, 2026*

Well made. I used it to disconnect a battery on a motorcycle. Can’t find a dead short.

### ⭐⭐⭐⭐⭐ Great batt disconnect for garden tractor
*by S***E on January 5, 2026*

Worked perfectly.

### ⭐⭐⭐⭐ Works fin as a cutoff switch.
*by M***N on July 13, 2021*

I use this to disconnect power to a 24v trolling motor that otherwise will drain batteries over a few days as the GPS and bluetooth head on the motor won't otherwise turn off. The switch works well and the look fits well with my old aluminum boat. It does feel kind of cheap .... but then it is inexpensive. Large heavy posts should hold up well.
