I use to pay a extra Premium $$$ for Extension Cords made by Yellow Jacket. That premium was worth it to me as their cordage was by far like no other cordage on the market !
Granted, I have a couple of DIY SOOW with Hubbel Ends.
Just got my premium priced Yellow Jacket worklight today
It is just like every cord out there - nothing special not like the old Yellow Jacket cables I know and love....hell, I even have their 100' 10/3 in a reelcord bucket and it's so flexible, it feels like a 12/2 cable ;-)
