AC Window Seal,Portable Universal Window Kit for Mobile Air Conditioner Unit and Tumble Dryer 400cm/158Inch,Hot Air Stop Air Exchange Guards with Zip and Adhesive Fastener

Really good, really easy to put up (used video on Amazon) and great price. Very happy!

That’s a great product as the zips don’t skid. Previously I’ve had to return items from other vendors because it wouldn’t hold the hose due to the zips skidding. This one holds the hose perfectly. It’s very strong material. 4 stars instead of 5 because the tape did come out in some places.

Velcro attachment to window works well, and is plenty sticky enough on upvc. It effectively reduces the warm air coming back in the window when hanging air con hose out of window. Fitting is easy, instructions provided are good. Decent value solution.

Brought last year. It worked perfectly and stayed in place but now the weather is warmer the adhesive tape doesn't stick at all and the kit has completely fallen down meaning the air con isn't as effective. We will have to buy an entire new kit unless I can find some replacement tape which is a huge shame.

Great kit that gives you everything for a decently sized window. Makes a good seal and is easy enough to put up and take down each time you want to use it.

Does it work: yesIs it easy to set up: absolutely not. we tried both the door version and the window version. Both were a huge pain to set up. And be prepared to spend some time cleaning glue/tape residue afterwards unless you use tacks for a wooden frame.Does it give an air-tight seal? : It does do it's job keeping most of the hot air out. But there are gaps. So when the aircon isn't running/ the edges of the window can let insects in.Does the Velcro tape work? : yes, but they are such a pain to clean afterwards, and don't really stick well especially with the weight of the aircon exhaust that it has to hold. you're better off using a different tape and just buying a whole new one next year after ripping this one out.Can you re-use this for the next year: arguable. The fabric isn't as great as the advertised photo that compares it to other brands. Your window seal will look like the photo of the other brands by the end of the summer for sure. If you are careful you can re-use this. But considering this is only $12 (when we bought it), you're really much better off buying a new one every year.

This item is not fit for purpose. One use then throw it away. Leaves adhesive marks on the frame. Very poor quality

We have only been using it this summer but it was easy to fit, easy to use and works well.Someone has obviously thought about the practicalities of using it as you can open the zip in two places so you can zip up around your hose and also open the zip in a seperate place to use your window handle to open/close the window.You can easily close your window without having to remove the seal as it just folds up as you close the window although it your that bothered it only attached with velcro so you can remove it if you think it looks bad.Reading reviews for multiple products i did see a regular issue with all these kits which we have encountered which is near the hot air exhaust the sticky parts seem to detach occasionaly but we this only seems to happen if you have it taught and they have always just stuck back on for us at the moment.Whether this works long term.i.e. we can reuse it next year we will have to see but it seems fine at the moment.
