Gruntbear Universal Window Seal for Portable Air Conditioner, Portable AC Window Seal Kit, Hot Air Stop Air Exchange Guards with Zip and Adhesive Fastener Works with Tumble Dryer (400cm/157inch)

Works for my window that opens outward. No idea about longevity. Why pay more If you dont have to

I purchased this for my old casement window and did the trick. Thanks

I have some older windows in my house that I wanted to be able to put a air conditioner vent out this was very easy to install very durable and works as it should

Other than the cheap glue to hold the velcro onto the window this product works well and is very easy to install. My house was built in 1961 and almost all the windows are original and kind of a weird design but I had no problem with the install. However, where the AC hose vents out the velcro popped off from the weight. The glue really doesnt hold up all that well. Otherwise a useful product which pretty much solved my AC dilemma.

Good product and fast delivery.

Very difficult to install and the double sided tape lasted about two hours before falling off. Dont recommend.

I cannot believe I never used one of these before now. This thing is a game changer super easy set up no bugs in just zip it up and forget about it

A+++++

Applying the seal was a nice and smooth process, however, the zip ties to keep it closed are too short to wrap around your exhaust tube. Not only that, the zipper is too small to loop it through.
