Great Extension Cord for hard to reach places.
Size: 5FT, Color: White
Wasn't sure if I would like this or not but I really do. We have the stand up version (not by same vendor) but really liking this smaller version that I was able to stand on edge and not take up valuable room on my side table. We used it for the outlet under the bed to the bedside table. Has enough power to run multiple items with no issues. I like that it comes with USB, C, 2 prong, 3 prong. I didn't use the included cover but that was because we had something else plugged into the other socket.

Decent
Size: 20FT, Color: White
I needed a heat gun to make it a little more pliant to get the kinks out but otherwise I loved it

Exactly what I needed!
Size: 20FT, Color: White, Size: 20FT, Color: White
This was exactly what I needed! Had to figure out a spot for the automatic litter box we have but the nearest outlet was 20 feet away. This outlet was the perfect length and I used 3M tape to secure it to the baseboard so it blended in!!

Good item
Size: 20FT, Color: White
Good item. The flat cord allowed me to run it around the baseboard with little visibility
