12-06-2025Good value. They were just as described. They worked great for the 4 gauge wire that I used. I crimped them and have had no problem. I would buy again.

> 3 dayExcellent battery/cable ends. The quality of these cable ends is obvious. Worth every cent. They also crimp extremely well. Spend the extra few cents and get the WindyNation brand, you wont regret it.
