  • Great for the price!
Size: 400CM
Overall, we are very happy with this purchase. The install was a little confusing because the directions are not very specific. Once in place the system worked great though. Our windows open outwards so the easiest setup had the zipper handles on the outside, which is not a problem for us because we can easily walk to the outside of our windows, but might be harder for someone on an upper floor. I think you could install the system on the inside of the window in this case but it would not look good. Aside from those two observations, I definitely recommend this product! ... show more

  • Does the job so far
Size: 400CM
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. ... show more

  • Easy to set up
Size: 500CM
Took less than 20 minutes to put on my window. There's videos on YouTube you can watch first to get an idea. Tape sticks well. Plastic is durable and thick. Now I can have AC in the comfort of my home. I highly recommend.

  • It works…but I wouldn’t give it a 5 star.
Size: 400CM
It does what you need it to do, seal the corners of your window to put in a portable ac. Material is fine and I haven’t had issues with it even when it rains. The sticky part took some time to stay on the rim of the window cause it would peak in some spots. Overall it works and it does what it is intended to do. Wish it was of better material. Because as soon as you turn the ac off, the room gets hot again. ... show more

  • NOT WATERPROOF

The adhesive on the velcro is not waterproof, it came off after one light rain

  • Easy set up
Size: 500CM
I have a window that opens outward. This is a great product! It only took a couple minutes to apply the sticky Velcro to the window frame and window. Then I stuck this on, and that was it. It works great. Highly recommend.

Worked perfectly. Helped cool our dorm room. Used it on a push out window. Took 15 minutes to install. Video online was useful

  • Works well, hoping it holds up
Size: 400CM
I have crank-out casement windows, 68x21" along the outer edge where I installed the velcro - so the largest option was not quite big enough for my windows (needed 178" and this is 157"). However, it still worked because I put the unsealed side on the closed side of the window. The instructions were for windows that open inwards instead of outwards, so it was a struggle to figure out how to reverse all of the instructions. Thankfully I found a good video on YouTube - look up the casement window seal video from Morozov Automotive. I don't think it's exactly the same model of seal but it did the trick for me. I've had this installed for a month now and I'm running a grow tent exhaust hose out of it. The zippers are a bit flimsy and I am not confident they'll hold up to long-term use, but I am in a set-it-and-forget-it situation so I won't be opening and closing them, so I hope it will be OK for a while. Also, the fabric of the window seal already has some pinholes showing up - not sure if they're from the stress of the window being open or if they were there at the start. The velcro that holds the seal in place is strong and I've had no issues with adhesion, even in the 100 degree heat. I have central air conditioning inside and I feared losing heat/cool through the window but it doesn't seem to let heat in. My room is the same temperature as it typically is with the AC set. We'll see if that holds true for winter, but I suspect it will be fine. As far as rain, this window is protected by the gutter overhang, so it hasn't gotten very wet even in our rainy weather. So I can't attest to its degree of weather proofing if fully exposed. I do wish it had a better way to install a vent. As is, I run the duct tube out through a hole made between the two zippers and zip them up to the tube, but there's nothing to hold the duct in place and the zippers leave a gap above and beneath the duct. It's big enough that bugs can get in (maybe the diameter of my thumb). Overall I'm happy with it - it does not obstruct the view out the window, and is working as intended. ... show more
