Worked great for boat install
Size: 30ft, Style: 10 Gauge
Bought this to run some accessories on my boat. Worked great and well made. Flexible even with the coating. Made for easy work and should last. I wouldn’t hesitate to buy again if needed.

Sturdy and works great
Size: 15ft, Style: 8 Gauge
Used this for an approximately 8' run in my electric UTV to power a 2500W inverter running off the 48V batteries so I could power AC tools out in the field. Very thick casing and nice and strong, but flexible enough to route around the frame of the UTV.

Insulation and outside cover materials tough to cut and strip.
Size: 30ft, Style: 10 Gauge
Made in China. Wire works fine but the materials used for insulation and the outer cover are a pain to separate and strip for use. This isn’t like Ancor wire!
