### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    They work great but covers don’t close
  

*by M***A on Reviewed in the United States on October 13, 2024*

The trailer cables are too thick for the little cover to close over them so I used zip ties to keep it shut for the most part. I will end up with the same problem of rusted connections and loss of power eventually, but at least I know it’s an easy fix now.  They aren’t waterproof.
