not big enough
The idea is good, but they are not big enough for the standard outlet/switchplate. If they were just a little bit bigger, they would actually function as intended. I still used them and just caulked around them, but it would have been much preferred if they were sized more generously. Also would be good if they had them in individual styles (e.g.: a package full of only blank ones, a package of only outlets, a package of only deco switch, etc.) So I would recommend them only if you have exceptionally small outlets, but not if you just have the standard size or the oversized ones.

Mmmm, not impressed
I had to whittle on these to get them to fit behind the wall plates. Made in Oklahoma City, but I think I could have gotten craft foam from the hobby store to fit better.

the item was okay, but I had to take a rubber mallet and hammer it flatter. The switch places kept sticking out with them on it. you may also need to cut to fit better

Does not really work
Still feel the cold air coming in through holes and light switches. Little to no effect. Maybe minimal.

Good product, No Decora cutout
These are a really good deal, and they definitely work. I recently replaced an old metal box with a smart box, which being a replacement was not plastered into the wall like the old one. I immediately noticed significant air flowing through. This cut the flow way down. Only complaint, I've seen some other insulation inserts with cutout for Decora shaped outlets as well. That would be useful. I was able to but out the Decora shape, but nicer to just pop them out!
