Review on 🦆 Duck Brand Socket Sealers Variety Pack with 16 Outlet Sealers, 6 Switch Plates, 2 Decorative Covers in White - Model 283333 by Josh Garber

Yes, yes, yes, blah blah, the hole is more than an insulator and it's not optimized for anything. See, people like to think they know something through their "intuition" and "experience," but the reality of heat transfer and thermodynamics is more related. Put them in and stick a sensor nearby to actually register the temperature. You will see the temp change to 4-15 degrees depending on how drafty the tanks are Most of mine didn't "completely cover" the holes and I still had great readings Just a 1-2 degree drop? they are there. But double congratulations! They're cheap so you haven't wasted your money. My only criticism is the variety but I can't put an end to that because you were told exactly what you get: 16, 6 and 2. My B specifically has the house more than the included switches (relative to everything else) so I am ordering 2 more of these boxes. I'll have some sealant for the sockets, but they're cheap and I'm fine with that. of "How about switches that are like 4 for one thing?" So let them overlap a bit. I did that. And I had no problem getting them in with that little extra thickness because of the overlap. That's fine. It works.
