Review on High-Performance Stranded Primary Automotive Electrical Temperature Cable by Marc Stewart

Good product. It is actually tinned with copper on the outside, unlike most other products which are made of copper clad aluminum (CCA). They're actually solid core, not stranded, so they're a little harder to bend and manipulate, especially with crimp connectors, but if that's what you're looking for, you've found it. I have used them in a solar panel and am now happy with the product.
