Portable Air Conditioner Window Seal Kit, 400CM (157'') AC Casement , Hot Air Stop Air Exchange Guards with Zip and Adhesive Fastener Works with Tumble Dryer, Keep House Cool

Love this thing, I have one of those weird windows that opens from one side like a door and had no idea how to fit my AC hose through it. This was insanely easy to install, the Velcro sticks so well to the window. Make sure you clean up with a Lysol wipe first though - if your window sill is dusty then it won’t stick as well. Stays put all summer, great quality - even through crazy winds and rainstorms here in Seattle. Minimal leaks around the hose.

Easy to install and works well.

We have crank windows that open outwards and wanted to use the portable AC on really hot days.Installation was ok once I figured it out. The instructions are absolutely useless. But there was plenty of material to fit my large windows. It seems pretty secure once I got it on. The included zip ties to secure the vent were to short and my AC vent doesn't seem overly large. Luckily they included 2 zip ties so I eventually got it to work.So far so good in performance. We've only had a couple light rains so we'll see how it works on a heavy shower eventually. It definitely lets some heat in since it's just a thin vinyl fabric, but we closed a curtain in front of it and it seems to do nicely.Overall, it does the job as intended, but I have some doubts on longevity since it is pretty thin and only held on by Velcro tape.

Product was bigger than needed. Also cannot stay put sticked to the window in some corners despite not creating any pressure on opening the window. Otherwise a good product.

Doesn’t hold to a regular 70-80F heat. It melts and then everything falls apart so it doesn’t cool down the room. A waste of money and time because it is time consuming to install.Find a window cover made of plywood or plastic instead.

It works really well. The directions were easy to follow. It keeps the cold air in really well. Wasn't damaged during transportation.

It works as expected - keeps the wind out and the cool in.

This is one of the easiest items I have ever used! Installed very easy. I Love that I can easly take out the hose and close the window ths the flexible fabric still attached!
