Joypea 400cm Window Seal for Portable Air Conditioner and Tumble Dryer,Sealing AC with Zip and Adhesive Fastener,Easy to Install - White

It took me 90 mins to install, simply becoz of the stupid bars that my window has before it. For normal windows it would take 30 mins i guess. Seems to work good, and hot air doesnt come back in. But i dont know how durable it is over time. Will update after few weeks. But i dont know how to tidy up the excess tarp, as my second picture shows.

The window kit is ingenious! During August I lived in a dorm at the University of Washington for a post-graduate program. The old dorms had no AC and terrible ventilation. Further, the air was filled with smoke from wildfires. Air conditioning and avoiding open windows was a must. Without the window kit I would have been out of luck and would have hauled a very heavy and expensive AC unit for nothing. The window attachments that came with my Black & Decker portable AC unit didn’t work at all. The directions were easy to follow and worked very well with the push-out windows. After 2 weeks, the adhesive-backed Velcro came off with minimal effort and showed no signs it had ever been stuck to the window frame.

Soft yet waterproof and wind proof material. We are sad that it's no longer in stock as we wanted to order 2 new ones for the upcoming year since ours got quite dirty from wildfire smoke. These are wonderful quality and are super quiet. I purchased 1 of another brand and everytime the wind blows it's super noisy - joypea is so quiet and nice material! Velcro and tape top notch and very easy to install.. Highly recommend.

Product looked better than I imagined, however it was hard to install and a lot of bugs got in through the zipper cracks. I had to go to a plastic shop to have a better cover made and threw this one out.

I live in an old apartment building so this came in handy with trying to install an AC unit before summer. It was a little tricky getting in on my window but I did get it to work and I’m glad it’ll do the job.

Who created this gets mad props. Exactly what my new apartment window needed in this tight space. After a week, it's still holding up really well with my Frigidaire apartment room machine. I'm cold again!

It was a bit difficult to install because of the instructions so I just winged it, it was hard to figure out where to begin but it works great, I love it. No more hot air coming in

Took a long time to install it. The package came with a 1 sheet letter size instruction and all the tools in a ziplock bag. Took awhile to install it and later realized its not worth it and it was really loose and it was way too long. Ended up taking it down and throwing it away. (can't return because we used up all the adhesive to install the sheet)
