Well made.
Color: Black, Size: 6 FT
I bought a version this product maybe for years ago. Suffice to say that the outlets were too loose. The plugs rattle around and regularly lost electrical conduct. Not a problem with these.

Measure first saves time!
Color: White, Size: 6 FT
I liked the product but didn’t fit my vanity and my wife said to send it back that it wasn’t needed for her hair dryers. Great idea just wrong for me.
