Works well for open out windows
Purchased to use with a portable air con unit. My windows all 4 sides using window frame surround as my measurement was 286cm so I purchased the 300cm(3mtr) hoomee. This was more than enough. Instructions were clear but the basics are cut double sided Velcro to fit around window surround then as my windows open out attach double sided Velcro on inside of window frame. Then attach the hoomee sheet as per instructions making sure you start at your window handle by middling the sheet and simply attach to Velcro.Positivesgood adhesion to window frame, hoomee sheet is strong and well made and Velcro is good quality. Allows you to habe this fitted all year round as window will close when fitted.NegativesAll I can say is having a sheet round your window isn't the prettiest but you can detach the sheet from the velcro if preferred but as I haven't I won't comment on how good fixing and unfixing may affect the adhesion but will say I don't think there would be any loss.

Does the job nicely with great fast after sales support
Updated my review following a fantastic experience with customer services. They were extremely helpful and quickly identified that the information on the listing wasn't accurate for my type of side opening window and also sent a video to show the quickest way to fit it. They quickly arranged a replacement which has been fitted and seals all 4 sides completely. Only issue is the zips are a little lose so the hose sometimes comes lose but have wrapped a towel around mine to keep it in place. Does the job nicely and reduces heat from the hose coming back into the room. For the price it's really good and the fabric and velcro is very strong and unlikely to rip like some cheaper versions I've seen.Looks a mess, doesn't really fit properly but does seem to help with the heat generated. Don't think it's really designed for a side opening window. Didn't understand why you only measured 3 sides when it sticks to all 4 either.

Works for our window perfect
Our windows are the casement windows and open like doors, our portable air conditioner standard window kits could not fit our window. The cool air escaped to the outside through the window and wasted energy. The conditioner is fine, but without window seal, it didn’t really bring much cool air in my room. I could say, this window seal works great. The zipper is high quality and the cable tie is strong enough to hold the exhaust hose very well. And the seller provides the instruction manual with the installing pictures, making it much easier for me to understand how to install it. It is a very good investment, I’m sure it can save our electricity cost a lot for the coming season.

OK once installed, but a faff if your window has any fittings. Needs to be right first time.
The product itself is well made and does the job so would have been 5 stars if it was as simple to install as advertised. However I cannot give it more than 3 stars due to the unclear instructions and the difficulty in installing it around the fittings of my window.Firstly, the velcro really sticks and WILL take the paint of your window and frames, so you need to stick it in the right place first time. However, this is tricky because unless your window is exactly the same as that shown in the product's idealised pictures it's not obvious until you get it fitted exactly where you need the velcro. Anything about your window that is slightly different to the ideal version shown in the advertisement will distort the path that the velcro needs to follow. For example, my window has a closer and a large handle and locking mechanism so it took some experimenting to find the right position for the velcro.So in my case I followed the instructions (which are really poor by the way - you'll need to watch their Youtube video which is much clearer) and stuck the velcro first, but as the top and bottom (sill) of my casement are horizontal (not vertical like the instructions assume) the cover has to twist through 90 degrees in two directions at each corner which distorts everything as well. When I tried to reposition the velcro to adjust the fit then the paint was pulled off in large patches.My recommendation is to use bluetack or something to stick everything in place temporarily whilst you adjust and make sure everything is in the best position, BEFORE taking off the backing paper and sticking down the velcro permanently.

No more bugs in my house when venting my Air Con. great product
With all the hot weather we have been having this summer this kit has been a godsend. No more bugs and fly's coming in through the window. This allows me to vent my Air conditioner with peace of mind. Very simple to install and everything needed is included in the kit. The vendor even sent an email after dispatch with clear instructions. Simply attach the velcro on 3 sides of the window and frame then attach the seal. It is zipped to allow the pipe through and gives a good seal. Good value solution to stopping bugs.

Expensive for what it is, but does help
Here you're essentially buy a strip of material with a zip, and some velcro and velcro tape.The idea is the material creates a seal between the window and frame so that the hot outside air doesn't get back in, yet the air can escapre out of your aircon exhaust pipe.This can also be used for a tumbledryer, but to be honest, not sure how many people would run their tumbledryer like that.At £21, I think it's very expensive for what you're getting, but must admit that it definitely works better than not having it, so despite the price, the efficiency gain would probably make it pay for itself in the long run. Also the aircon just works for effectively and can actually maintain a lower temperature (hot air getting back in more readily otherwise). Do you feel like you're getting value, probably not. Do I regret buying it? - No, it doesn't look pretty and seem good value, but it has served its purpose.

doesnt fit window
I measured my window before ordering the right size. The tape to stick on the window fits and there was enough for that. But the fabric that attaches to this tape was not big or long enough to fit around the window. i tried multiple times, taking it off and putting it on but there was no way. There is a big gap now so the warm air can still come in. Because there was very little of the fabric, it was tight so opening the window ripped it off the hook tape

3 of 4 zijden meten
Er zat bij mij geen spleet waar lucht doorheen kan komen tussen de kant waar de raamscharnieren zitten en het raamkozijn, waardoor ik uiteindelijk alleen de 3 zijden van mij raam hoefde af te dichten. Had hierdoor dus een raamafdichting nodig die voldeed aan de lengte van de 3 zijden en niet van de 4 zijden zoals normaal zou moeten. Hierdoor was ik even in verwarring, maar hiermee geholpen door Hoomee klantenservice en zit nu allemaal goed. Een uitstekend product voor de rest.

Bon produit pour isoler une fenêtre avec climatiseur mobile
Très satisfait de ce tissu de calfeutrage.Franchement, je suis très content de cet achat. Le tissu de calfeutrage est assez simple à mettre en place et l’installation ne pose pas de difficulté particulière. Une fois installé, ça tient bien et ça donne tout de suite une impression de produit pratique et bien pensé.Pour le moment, il semble faire correctement son travail et aider à mieux isoler l’ouverture de la fenêtre autour du climatiseur mobile. Je n’ai pas encore eu l’occasion de le tester pendant les très grosses chaleurs, donc je préfère garder un peu de recul sur l’efficacité maximale, mais les premiers résultats sont vraiment encourageants. Honnêtement, je reste très confiant pour la suite.En résumé, c’est un produit facile à installer, pratique au quotidien et qui semble efficace. Pour l’instant, je suis pleinement satisfait de mon achat.
