### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent quality solid copper wire
  

*by K***E on Reviewed in the United States on March 24, 2024*

This is good stuff. The jacket is very flexible. as you can see in the photo, after taking a grinder to the wire, it is true copper, Nice tin platting. Diameter measures true. I was pleased to see that this is not a low quality knockoff type marine wire that would be questionable if you push amperage through it. This is the real deal
