Great way to turn off battery
Used to turn off your battery / save the battery life. It was super easy to install and works as intended! Highly recommend if you want to keep up battery life, but I use it to help me turn off my car (kind of weird but was looking for a specific product since my ignition column is a bit messed up #usedcar)

Inexpensive but effective
I installed the disconnect on my boat battery negative post. It fit securely and it cuts off power by rotating the knob.

Works well and is a very reasonable price
I have an old convertible that has to be stored in the winter. When stored, I disconnect the battery and put it on a trickle charger. I must have a short somewhere, because even during the summer when it is getting periodic use, the battery will sometimes drop down too low. I used to disconnect the battery if I wasn't going to use the car for a while, but that was a pain because the terminals can be hard to get to.Then I saw this cutoff and decided to try it out.The installation wasn't bad, the hardest part was because of the car rather than the disconnect switch itself. It works very well. Now I don't have to mess around with taking the terminal connectors off or any of that. I can just turn the handle and connect or disconnect with no problems. I can use the disconnect for short term or long term storage and it is saving me time in both situations.I was also able to position this in a way that conveniently worked for the car's teeny battery compartment, so it should fit just about anywhere if I could manage it in there.

Worked for My Tractor
Inexpensive battery disconnect.While I don't think my tractor uses any power when turned off (no radio etc), I wanted to ensure no battery drain while not in use. Since I was putting in a new battery and setting up connections for a maintainer/charger I though it would be nice to include a disconnect for periods of non-use or when charging or maintaining the batteryThis fit the bill without spending much money. Well made and fit perfect on standard top battery posts.Can recommend and would buy again.

Best purchase ever!
Purchased this item for my 1929 Model A and it works perfectly. Best purchase I had made since I have a small power drain on a 100-year-old vehicle I drive 10 times a year.

Not as advertised . Very weak material
Not as advertised. Metal very weak and broke in 2 pieces with just mild pressure from my hand when installing on terminal post.
