Portable AC Window Seal Kit 400CM/157 for Casement, Crank-Out & Skylight Windows, No-Drill Window Vent Kit with Adjustable Zipper, Fits Single & Dual Hose Portable Air Conditioners

Works and looks great!!!

Held up in full sun for entire summer. If you shut off your ac when it is humid, the adhesive may release on one side. We found that reinforcing with weather seal tape addressed the issue. It gives enough extra that you can easily fit it in a window. I recommend installing from top to bottom and on the straightest part of your window first. It is not hard to install, but it depends on your ability to peel carefully and how well you have cleaned and prepared the area. It did a good job of keeping the heat out, but I recommend also purchasing an insulating sleeve for the AC unit inside to get the full benefit. It is the same thickness aso one of those stuff in a tiny pouch windbreakers. So it's thin, but does what it needs to do. Good value for the money.

Works perfectly for my older swing out window. I don't have central air and my room is upstairs so it gets pretty hot in the summer, too hot for just fans. I'd given up on using a portable AC because of the difficulty sealing off this type of window but this seal did exactly what I needed it to do. I highly recommend this kit!

Got the wrong size but it still works for us so no need to return! Thanks

Seems to work, bar a few complications, but my cat can DEFINITELY escape though it if she ever got curious. Currently looking to invest in an acrylic panel with a hole for the hose to replace this but it works for now to test the new AC. (Just being very very aware of it and my cat.

The one I bought was a bit too long. But it’s okay! Still functional. I bought this because the tape and box around my window didn’t look nice and it’s not weather proof. I like the flexibility of this item because if it rains all I have to do is remove it from the stick on Velcro and then re-apply again later if I want. Functionality: I like that it’s somewhat rain proof, and you can remove anytime and reapply if needed Stickiness: Make sure you follow instructions and clean your window seal well. Or else the Velcro adhesive will not stick.

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.

Had it for almost a week, little bit bigger than my door frame I installed the adhesive velcro on the wall just outside the frame. Probably will take some paint off when it comes to uninstalling one day, but I am ok with it. Likely just replace it with a new mesh so not to worry. Most importantly, my wife approved it......

I had a neighbor install the unit. I have not used the door since purchase

fairly easy to use and put up. Wish that there were more magnets along the center to hold it together better.

Great product for the right application

Easy to install without having any tools .
