## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Fairly easy install and works great.
  

*by G***T on Reviewed in the United States on October 9, 2024*

While it will function for it’s designed anti-theft purpose, I found it useful as a temporary solution for an electrical drain that had become difficult to resolve. My classic VW Beetle would lose charge and the long term solution will probably involve a new wiring harness. This device gives a cost effective quick fix and since the battery is located under the rear seat, it is greatly simplifies disconnecting the battery.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works well - Easy to Install
  

*by M***E on Reviewed in the United States on August 29, 2024*

Had a very slow parasitic drain on the battery of my '94 Lincoln Town Car.  This device was easy to install and works very well.  Keeps me from having to recharge the battery every few weeks.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Very easy installation, good features
  

*by R***. on Reviewed in the United States on April 26, 2024*

My 1980 MGB has its battery located in the cabin in a compartment behind the passenger seat. The need for a battery disconnect is predicated on the fact that this car is only used in the summer months and even then, is only a fair weather cruiser. The disconnect will help make sure that the battery has a full charge when I want to start it. I wanted a battery disconnect switch that was easy to access, robust and, hopefully, easy to install without drilling holes in my car. This unit checked all of those boxes. This unit was a bit more expensive than most others but, since I didn't need to buy at least one additional battery cable to hook it up, cost wasn't much more than a quality, conventional disconnect switch. And, when factoring in ease of installation, this one seemed a clear choice. It works completely as described and I can keep one of the key fob remotes handy for ease of operation.I hope that it works many years in this classic, British sports car.
