## Customer Reviews

### ⭐⭐⭐⭐⭐ Simple Battery Disconnect
*by M***T on December 5, 2023*

It is easy to install and does what it claims to do, I have used others on Amazon with less-than-stellar results. I would recommend this one as my goto disconnect.

### ⭐⭐⭐⭐⭐ Pretty straightforward.
*by K***K on December 31, 2023*
