OUTSTANDING!!
Exactly what I needed to plug the venting on my downdraft cooler for the cold winter months. Perfectly sits in the cavity, holds easily in place from friction, and stops the cold air from coming in and warm air from going out.

What a Difference!
I have a pretty small vent opening. 13 1/2" x 17" and this insulator pillow fit wonderfully. Nice snug fit and easy to install. No breeze coming through that I could tell. Temperature jumped up immediately. Didn't measure the exact amount but I could tell the difference. I would recommend this product!

Good item.
Looking forward to keeping the heat in. Pillow a bit bigger than opening but needs to be to completely fill the opening with the insulation.

Actual Size Incorrect
Actual size is more like 20x20x4 as stated on the package. Verified the item number. The cover is durable. Have not installed it yet. It looks like it will do the job.
