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)

If your city is hot, then these will not only melt off your window but make a sticky disaster everywhere. The application is easy but still is tricky to position everything without openings. Not great overall.

This is supposed to be for a window that cranks IN. Mine cranks OUT (I have never seen windows crank in). I made it work and it works GREAT!!! You just have to remember to close the window before it rains, so the rain doesnt pool on the top.

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

originally i bought the 300 cm bc my son said it was small casement window but after it was measured, realized needed to 400 cm one so quickly ordered the longer one and returned the smaller one. see photo of how it works with outward swinging casement window. can’t really comment yet on durability but so far works well enough to keep bugs out and cool A/C in

I liked the seal, seems to be efficient . The Velcro holds good make sure to clean the area before you apply the stick Velcro. It def works

I got one of those Dalek air conditioners, but it had no venting tubing and the plastic hose connector was broken. Epoxy and new parts made it work, but it was a trick to vent it out a tiny pantry window. I really expected this kit to be a mess to work with, but it was easy. It doesnt stay put quite as well as I had hoped, but that may be because it was hard to get rid of all the kitchen grease at the edges of the window frame.

I have crank windows in my house and I absolutely hate them, but theres no changing the windows. It doesnt get hot save for a handful of days through the year so nobody has A/C. We got an A/C unit and also got this for the vent out the window. It was NOT easy to get the Velcro on there. It also was damaging to the pain around the window because the glue on the Velcro is no joke strong. The strength of that Velcro is worthy of a star. Once I had the Velcro I attached the seal and the A/C unit vent attached. It was a pretty big disappointment. Having the window open with this shield attached just let ALL the heat in letting any cool air the A/C unit produced go out. Maybe my window is just too big but it was much smaller than the dimensions of this seal. The material of this is just too thin and would be better if it had some insulation to it.

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.

Does what it’s supposed to do, no issues at all
