Rated 4.0 out of 5.0 by WilW They work great in old houses.
Every square inch adds up when trying to insulate a home and a few packs of these helped me out. my living room is noticeably less drafty now. Only wish is that they sold each type separately. Ended up with a surplus of the rocker switch ones.

Rated 4.0 out of 5.0 by wgb For a leaky house, well worth the money.
If you have a lot of two and three gang switch boxes you will have to do some cutting. If the manufactures would think of this, they could pre-punch some of the cover gaskets to fit multiple gang applications.

Rated 5.0 out of 5.0 by dc8flyer They work, but one more item needed to completely seal outlet
The product itself fits snuggly around any socket or switch and prevents airflow into or out of the particular switch or socket.
I also used this product to insulate the phone jack plates. These plates however are wide open where the phone line used to plug in so a bit of masking tape covering the phone jack connection completely sealed the draft. I used one of the many electrical plug outlet insulators and a pair of sissors to modify the insulator to fit the phone jack plate.
However, while the plate is insulated the air flow still remains and seeps through the plug outlet itself. The holes where the plug actually plugs in allows air flow in to or out of the socket. I found I could successfully stop that airflow by using this product from Home Depot:
Safety 1st Ultra Clear Outlet Plugs (12-Pack)
These plugs fit very tight when installed and block off all air flow from the three holes of the plug itself. There was a noticable differece before and after the installation of these plugs when I held my hand up next to the plug.
A 12 pack of these cost a little over two dollars and makes a significant difference when used with the frost King socket insulators.

Rated 4.0 out of 5.0 by Richierich03 Work good but not perfect!
Thus is a good insulating product but it could be better. I found it best to caulk around the switch/outlet boxes before using this product. It seals good but some air still comes around it. Had to use some duct tape to seal completely. Still better than nothing but could be better.

Rated 5.0 out of 5.0 by Geezer Very good deal
These are much less expensive than other brands but the quality is great. They will cut down on heat loss in winter and heat gain in summer. All this for $3.00!!

Rated 3.0 out of 5.0 by Patti Good product, size slightly too small
Went ahead and bought these because the other insulator's didn't look very insulating. These are good quality but would be much better if 1/8" bigger. I also used spray foam around it to reduce leaks.

If you want to start saving on your winter heating bills, then I would recommend using these sealers behind each and every wall outlet or switch plate. They really do help to keep out drafts and reduce heat loss. Easy to install, durable, and of course, they are Frost King-the name you trust.
