Outdoor Window Air Conditioner Cover

I should have listened to the reviews...this does not cover the bottom of the air conditioner so the second the wind blows, it flies right off the air conditioner. I bought two and lost both on a not-so windy day.

Blew away. Never could find it.

We have a air conditioner that lets a lot of cold air into my apartment. I used this cover at an inner liner and put another cover, that is a little more attractive, over it. This cover fits tightly, with the adjustable elastic, strap and seems to block out the cold air quite well.
