    I was so relieved to find this so I could use a portable AC with my stupid crank windows. This thing is really simple to use and gets the job done. Only complaint is that the Velcro isn’t super sticky: I had to reinforce it with duct tape in several places. Not the end of the world though and still highly recommend if you need to make a portable Ac work in stupid windows

    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 just what I needed for my single hose portable A/C (though I see it can accommodate two hoses if needed. It is a bit odd to contemplate and visualize at first (I thought), and the illustration with the directions I found bizarre, but the product itself is a great quality and very logical in how it attaches to my window. As the circumference did not quite reach all the way around my window (I did not want a larger size with a lot of gathering to contend with), so I just purchased white painters tape to complete the last 6 near the window hinge area and that seems to work great. Do pay attention and measure your windows.

    Not as described. Doesn’t show in pictures that it tapers which didn’t work for my larger opening even though under the size they mention. Velcro tape already peeling off a very clean flat surface. Junk really.

    Definitely useful to install

    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.

    I didn’t find the GRUNTBEAR WINDOW SEAL as easy to install as marketed – but then, again, I’m that kid who put square pegs in round holes. My installation dilemma was that my horizontal window cranked outward, positioning the actually opened window pane on the exterior of the house as opposed to inside the house; and the user’s guide and instructional video on this Amazon’s product page, demonstrated installation with the window extended inside the home. Nonetheless, after a few trials and errors, I was able to install the seal sufficiently enough to prevent air and flying insects from entering the house. The GRUNTBEAR WINDOW SEAL was adorned with dual zippers that allowed for four separate openings; meaning that I was able to provide an opening for the air-conditioning hose outlet with one set of zippers, and the crack on the window with the other set of zippers. The package also included enough adhesive velcro tape on the roll to complete the installation with tape remaining, and both sides of the tape were forgiving; I had to reapply a few pieces of tape several times in order to maneuver the correct placement, and the tape’s adhesive did allow for those initial mistakes and replacement. I was also able to open and close the window, with the seal intact. The nylon material of the GRUNTBEAR WINDOW SEAL appeared sturdy, and perhaps waterproof, but it hasn’t rained since I installed the seal to test that premise. Overall, I appreciate the design of the seal, and once I figured out the configuration of the installation, the appearance was definitely much more appealing than a cardboard insert, from inside and outside the house. I anticipate being able to use the seal for several summer seasons and the nylon appeared machine washable. I did, however, miss the step to secure the zippers with the included zip-ties, but the zipper remained in place without the ties anyway.

    Its definitely easy to install and an economical product to fix the window issue with portable ACs, but the drawback is that it will not stop the hot air coming inside the room. Once the AC is turned ON its difficult to check if its really closing the gap and blocking the hot air seeping in, but take off the portable AC unit and close the zips properly leaving the window on a cold night. Your room will be lot cooler than the remaining part of the house.
