300CM Window Caulking Cloth for Mobile Air Conditioner and Tumble Dryer - Works with All Mobile Air Conditioning Units, Easy Installation

Me encantó quedó a la medida y es de buen material aguanta mas de lo que imaginé y aparte no se moja

this is my second year of using this. The material seems to stand up well after my second year. I have vinyl windows and I think on my third year I will have to replace the Velcro strips on the vinyl window because they are peeling loose in the corner. But I got two years use out of it so far.

These work really well for making your window AC unit more efficient. It wasn't hard to install but it was a bit of a pain. It sticks really well (like really well...not sure what we're going to do when we move out because I don't see it coming off, but I guess that's a later problem).

Works great on our windows that crank outward.Customer service was awesome.Directions weren’t very helpful so install was slightly challenging.That being said install was easy in since that your just sticking up Velcro strip and attaching material to fabric.For sure was a game changer for the cooling ability of our portable a/c unit.Very pleased with the quality and durability of this product.Thankful to have something that works on windows that aren’t the standard type of window.

Works well for using with condo windows and portable air conditioner. Mine is a single hose design but the second opening is useful to work around the window handle which would create an issue. With the constant opening and closing my lasted three seasons before I pinched the plastic when closing the window, causing small holes to appear. Also eventually the seal does get dirty from outside pollution so it is a good idea to replace it. The price is reasonable so replacing it every three years of constant opening and closing is a good value. I remove it during the winter so it stays on roughly 7 months out of the year.
