One thing the Flex made me do was go over all my extension cords, found some flaws in all of them except one.
Most of the OLD ones were 16 AWE and they were OLD, like 25 to 30 years old.
I have one newer 100 FT 14 AWE that is still good. That one replaced an old 16 AWE 100 FT years ago that went bad.
SO I had to get a couple on new ones so I got a 25 FT and 50 Ft, both 12 AWE so I am set. (Replaced a 50 Ft and 2x 25 Ft)
