Bests & Worsts Reviews from Amazon

These actually work. I admit that I had my doubts at first, but then I verified the results with the Black & Decker TLD100 Thermal Leak Detector. Outlets that were at least 2-3 degrees lower in temperature prior to install were actually warmer than the wall after install. Pretty amazing. Package comes with mostly double round socket and a few square. Our house has all square, so we cut the round to fit the square plate and they work very well. We used the light switch cut outs for cable coax outlets which made a huge difference. The pictures are relative to current wall temperature right next to the socket.
