Very simple to install----WORKS GREAT
Have a auto that keeps draining the battery. Can't find out what is draining battery so put this in. Has solved my problem with having to jump car all the time. No more. Just flip lever and it fires right up. THANKS A BUNCH!!!!

Very helpful
Our Chevy truck has an electrical problem that drains the battery if it sits for more than two days. This is keeping it from draining until we can get it to a repair shop to fix the problem. It was easy for me to install: "Here, hubby, put this on the battery.". :) It took him a bit of time to get it on but it is on and works great. Haven't had a dead battery yet. Very easy to disconnect/connect with the flip of the "blade". This item was hard to find locally because of the side terminals. We had been disconnecting the negative until this arrived. Something like this can also act as a theft deterrent, if it doesn't start, they're not going to hang around to figure out why.
