Query: High quality extension cord!

This is a very good, solid cord. One of the best I have ever used.- Insulation is durable- True 12 gauge wiring- Sturdy, but yet pliableI don't like 100 foot long cords; so I got this 100 footer, to save money, and cut it in two to make two 50 foot cords.I love the lighted ends because it lets me know if the cord has power. The light is a good brightness and lasts a very long time.
