This was a solid purchase for a Big 3 upgrade. Plenty of length for my application and haven’t had issues with quality or current in months since install. Recommended.

### ⭐⭐⭐⭐⭐ Good quality for a CCA (Copper Clad Aluminum)
*by D***N on June 7, 2024*

This is good quality CCA wire. It is not OFC (oxygen free copper). Honestly though, I replaced it with OFC after about a month. Not because of any flaws or faults. Just because I wanted something better for peace of mind.
