Item is exactly what I wanted
Very easy installation. Works as it should. Will use this to prevent theft and to protect rig against fire if there is a short and I have to eliminate any connection to battery. Would buy again but expect will not need to unless I buy one for a different vehicle.

Good battery disconnect.
Simple operation. Clean mounted appearance. Set it up to interrupt the main ground cable to the battery. Feels very solid and durable. Terminals easily accept 2 cables.

Helps keep my battery from running down when vehicle is not used for a while
I have a pickup that for some reason slowly drains the battery when it isn't used for a while. With this disconnect switch I can isolate the battery, then turn on the switch and crank the truck when I need it. At first i thought it was defective because the battery terminal was bigger than the switch terminal. Then I read where it went on the negative or ground terminal, then everything fit well. So far so good.

Works as expected and easy to install.
I purchased and installed this switch in December of 2025 as there is an intermittent draw on the battery when my vehicle is off due to a wire harness issue. The switch is easy to install and it has been working as expected.
