400CM (157") Portable AC Window Seal Kit for Casement Crank Skylight Windows, Newest Waterproof Insulated Window Vent Kit with Flexible Zipper Design for Single&Dual Hose Air Conditioners, No Drilling

I have a portable ac with a terrible window to use it for, and previous years I shimmied cardboard together to make it work, and took hours to do. This year I decided to try something off of amazing. And this solved it perfectly. Hopefully it lasts

My set up might be a little janky BUT it works. Installed about a week ago. 4 out of those 7 days has been very very rainy. No leakage and temp has maintained very well. I’d buy again.

Works great - due to the nature of the product the seal could be better. For the price and ease of setup, I am happy with how it works. About 3 months of use.

Perfect for these hot days, this article makes it easy, the installation is quick and delivers on what it promises, keeps the air inside leakless, very useful without having to spend too much money

Exactly what I needed for my crank window.

Its entire purpose of the cover is to provide a seal in the triangular pyramid gap that forms with the push-out windows. But the sticky tape the cover comes with doesn’t work well at all, it peels off too easily even after cleaning/scrubbing the window frame it’s supposed to stick to. I’ve had to apply duct tape to the entire perimeter. Now my windows have the additional residue to have to remove after the summer.

Works well, easy to install, good quality

I have a casement window that opens from the bottom. I had just purchased this seal and I was having high hopes regarding this purchase, Even though I had read the review rating and it had not been what I was expecting. I was very excited to try this type of window seal, and when I tried to apply it, It took me over two hours. I love the idea of this design, but it did not work well with the application. Some say that it could be a user error when trying to apply the window seal, But after I had it in place, It started coming undone. It only lasted three days before the entire things started to unseal. I may be knew when it comes to these types of products, but it did nothing to drown out any noise coming from outside. I was able to hear the leaves when the wind blows, I could hear people walking, I could hear everything that happened outside. I had to keep my door shut to the space because I was afraid that anything that may hit the windowsill cause the contraption to fall. I understand that with a window seal, There’s going to be some sort of modification to the appearance of the room, but every time I had guest over, they always had to look at that window seal. To be quite honest, It’s not the prettiest of set ups and they appearance isn’t very attractive, but it gets the job done… Mostly. I still could feel on hot days that the air conditioning in the room was not cooling as it should, and I found out that hot air was coming in through the window seal. I like the fact that there is no magnets and that there is a strong adhesive. But it seems that the Velcro strong enough. Adhesive parts stuck glued to my window! So that was an absolute plus! They have Wonderful adhesive! The Velcro not so much. I wish they could revise this design because it is a wonderful idea just executed poorly.
