## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    It works
  

*by B***C on Reviewed in the United States on 4 September 2023*

Worked well in my ROADTREK camper

### ⭐⭐⭐⭐ 







  
  
    Good but short on parts
  

*by M***Y on Reviewed in the United States on 11 July 2022*

Just installed so can't comment on the durability, but it all seems to be decent quality material.  I will mention my power cable did not come with battery terminals on its ends.  Without those terminal ends and needing an additional 4 terminals to wire in the fuse holders, I ran short and had to make a trip to the hardware store mid-install which was annoying and takes some of the value out of this all-in-one kit.

### ⭐⭐⭐⭐⭐ 







  
  
    Great battery isolator, Easy install
  

*by Q***7 on Reviewed in the United States on 16 January 2022*

Quality parts at very reasonable prices. Everything you need to connect a second battery is included, and the included instructions are good. At the same time, you can see whether it is charging through the LED light, and you can see the current voltage by pressing the switch, which is very convenient.Great product!
