Really happy to find this product.

I have three portable AC units that l have installed, all possible because of this product. My windows are the crank kind, and there is no way to set up the exhaust and close a window on top of the vent panel. I have used this for three summers over three windows and this has never failed. It adheres so well to the double sided tape that is included and is really easy to use.
