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)

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.

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

Product does what it says , BUT the adhesive strips that hold it together are horrible and keep falling apart.

I have crank windows(that open outwards) in my new apartment so it has been very hard to use my portable AC in my bedroom. Using this window seal has been great so that I can keep the cold air in and warm air outside during use. I did have some trouble putting it up myself though since I am short and the window is above my regular reach. I had to have someone else help me install it. No other issues so far though.

Works like I wanted it to

My expectations weren’t high, I have to admit, but this thing worked great on my outward rolling-old type casement windows, much better than I’d even hoped, I can even close and latch the window with it completely still installed. Don’t know about durability yet, the installation wasn’t as bad as I had imagined either. A great answer to casement windows of any type. Mine were 17” wide and 47” tall.

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.

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.

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

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.
