Pretty good extension cords and they come with your info printed on them. They aren't cheap but good. I bought a bulk order and ended up getting a decent price. I think it looks good and avoids the "that's my cord" conversation.
Lighted ends is a plus and comes in all colors. I got all my 100' cords yellow and the 50' cords orange. Nice and bright to help avoid any tripping.
You may also want to order as a group and get a bulk discount. They have done that in the past with no issues with the printing.
