Wanted a easy way to disconnect the battery on my car. This is easy to connect and move the lever over to disconnect and it's done. Very easy and functional.

The device works fine, but would not fit in the small space where I needed to install it, so I had to return it.

extremely easy to install and test. made sure it cleared the hood no problem plenty of room. and close to side so easy to reach from the side. . parasitic drain was running battery down and had tried a twist knob style that was a waste of money. previous owner had one on a car i got to keep alarm from killing battery. that's where I got the idea to try one on the truck didn't work .. oh well once I saw this and read the - reviews I knew it was the right one to install. we were connecting/disconnecting with a small wrench and piece of wood. what a hassle. its all metal quality is a plus. works so easily and positively I am extremely happy with it and highly recommend it! wish I'd found it sooner!! no more searching for the wrench and flashlight at nite or ever. and I installed it in about 3 minutes or less one - handed! , as I said extremely easy to install. & it works , glad I got it!!

Put it on my classic Mustang. Previously I'd pull the battery terminal off. that took time and ruined the moisture seal on the connection. this went on in 4 minutes, works good.Two thoughts: these can be lefthanded or right handed, easy to switch it to the configuration that fits you car best, keeping your existing wiring arrangement. Also be sure you have enough clearance between the switch and the your hood.

I purchased one of these months ago and have over the last few months ordered 2 more for a total of 3. I have one for two of my vehicles and my 1952 8n Ford tractor. They are well built and are very easy to install. It is so much better to just flip a lever instead of having to undo and redo battery terminals. Especially since 2 of the 3 are not used on a regular basis.

This is my second purchase of the same product. I first placed one on my 1965 GTO due to the fact that it is not driven that often and it works beautifully I would recommend this product to anyone with a top post mount battery. Only takes five minutes or less to install and it works perfectly. I then purchased one for my C-5 Corvette coupe which is also not driven that often in the last four years I’ve replaced the battery for the third time recently and this will eliminate the high cost of new Car batteries. Again only a few minutes to install and works perfectly.
