Customer Reviews on Amazon

Fantastic alternative to hiring an electrician to put in floor outlets!

I purchased this cord to power a recliner loveseat which was in the middle of my room; cord is perfect under a very low pile area rug, you can’t feel it at all. No issues with standard USA outlets.

It's very very thin and works exactly as expected. Seemed like a lot of $$$ for a cord, but once I used it for my application and it worked I realized it was a bunch cheaper than an electrician.
