It helps keep my home warmer. It has a built in plastic lining. Will be ordering another set for a secondary residence.

This cover fits perfectly over my wall unit ac and secures with a concealed drawstring. The adjustable straps keep it snugger on the unit.

The product is very cheaply made. Fabric is super slippery and just slides off. It seems like it would stop a breeze from coming in so in that regard it works but i'm not sure if it was worth the hassle.

It doesn't fit, the hole for the cord is on the left side not the right. It's diverted from the bottom of the ac. Even though it appears to be the exact dimensions of my a/c unit, the corner keeps popping off, causing the whole thing to come off.

My small window air conditioner protrudes 5 into the room. Amazon's lg 6,000 btu unit is not 7. Lg.
