## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Extremely well built with good materials and safety cover; stainless hardware.
  

*by G***G on Reviewed in the United States on December 6, 2019*

Used these directly on several 100Ah batteries in a cabinet (non-marine).  Not mentioned is the fact that the brownish material on bottom under screw terminal is actually some type of very hard plastic that is insulated.  You will see all four of them in my picture.  Mounting upside down worked here.  Covers stay on.  Highly recommend.  Shipping is cost-effective (not oversized box).

    Works as expected
  

*by R***Y on Reviewed in the United States on May 15, 2022*

Used this to wire in my bumper winch on both of my Jeeps. This is one of the easiest ways to add a fuse and change the amp rating without changing any wiring.
