Review on Dottie WPI100 Wall Plate Insulation Gasket, 100-Pack: Enhancing Electrical Safety & Efficiency by Stephen Chowdary

I bought it after an energy audit at home. My examiner explained to me that in winter I lose a lot of heat through vents on the outside walls. I knew they were right because I could literally feel the cold air coming out of the outlet/switches. Not all sockets and switches were that extreme, but I could see the evidence in the thermal imaging camera. After a lot of research they turned out to be the best option as I could punch any hole I wanted and not have to buy separate sets and have leftovers. While I didn't always stamp them in correctly (the little triangles around the two sockets often came loose unintentionally), they were easy to use and install. I will give the additional materials to a family member so they can use them too.
