Amazing product good quality wires heavy duty remote control and it installed right next to my battery it kills the power with the push of a button so simple to install

Mech said it would cost at least $100 to identify the leak that was drawing down the battery on our old Jeep, and it might cost hundreds more to actually fix it.This did the job, and it took about five minutes to install. Works perfectly. BONUS: adds a level of security!

This is my first-ever product review, over the years since I’ve been a shopper on Amazon. My advice is: DO NOT BUY this product because it does not work, as expected & as advertised/ described under the product information. I purchased this product last August but just got around to installing it this March - 2025. It worked only once after installing it. Tested it the following day as I got to work and tried to disengage the relay using the remote control, it failed to disengage. After work, I picked my daughter up from school & as we headed home on a busy road, the car suddenly & unexpectedly lost all power & died at the stop light in the middle of traffic which I believed exposed us to grave danger of being hit from behind. Luckily, I managed to remove the relay and & was able to reconnect the cable directly to the battery terminal which allowed me to start the car and continue home. The device has not worked again since then. That whole ordeal was precarious & scary to say the least! Just a word to the wise!!

I had a huge problem: something was draining my car’s battery even when the car was off. I took it to the dealership who said it would cost between a few hundred and $1000 to fix as they’d have to go through each individual part to determine what was draining the battery. In the meantime, I’m having to unhook my battery every time I shut my car off and hook it back up when I had to go anywhere, which is in the trunk, so I couldn’t even close my trunk as opening it required battery power. Can you imagine what a hassle every trip to work, the store, and everywhere else was?! Then I found this device. My mechanic installed it for less than $100 and now I only have to use the fob to turn my battery off and on. No more dead battery, open trunk, or dirty hands from working on a car before work. It was easy to install and it’s still working after months of use. Huge problem solver!

My sons Jeep has a slow drain somewhere, in his electrical system and if his battery is hooked up, and he doesn’t drive for a few days, it will drain his battery to the point where we have to jump it. It’s not a big deal. Jeeps have been known for having glitchy electrical that can do odd things, and it’s a pain to diagnose the problem. He doesn’t want to pay a bunch of money on it because it’s older, and his first car, so we just disconnected the battery cable after driving if we weren’t using it again for a while. My brother suggested I get a manual switch to make the process easier. While looking up the manual switch, I came across this one. This seemed like a much better option, as he will no longer have to pop the hood every time to connect/disconnect. Installation was easy. The instructions are a bit vague, but anyone with basic car knowledge will be ok. It comes with 2 remotes, so we just push the button to disconnect the battery, and when we go to drive, push the other button. We don’t have to mess with any wires, use tool, or pop the hood when we need to drive now, just push button and we are good to go. I gave a 4 because there was a copper piece that didn’t have any instructions for it, the red wire is a bit flimsy, and the device feels like it could have been made a little more durable. The price was right though.

Easy to install. Work as needed.

Great product conserve your battery with the push of a button

Worked good for 2 days and then my car just wouldn’t start anymore. I disconnected the kill switch from my battery and it fired right up. The lights on the key were blinking when trying toTurn the battery on with the kill switch attached but nothing happened. I’m confused on if it was the battery in the remotes or the device itself, but it stopped working for me.
