Review on 🌬️ Frost King AC2H Outside Window Air Conditioner Cover 18x27x16 - Fits up to 10,000 BTU - 6 mil - Gray by Collin Donahue

Yes, this item is made of canvas material. Yes, belts are not secure enough without other straps or belts. yes downstairs is open Yes, it's made big. However, I was aware of this when I bought it. I had already planned elastic cords and a garbage bag (for the floor) for the winter months. I don't think it's advisable to leave the lid on when operating/using the air conditioner, but I'm no expert. I would recommend it to anyone on a budget!
