300CM Window Seal for Portable Air Conditioner And Tumble Dryer – Works with Every Mobile Air-Conditioning Unit, Easy to Install - Air Exchange Guards With Zip and Hook TapeGlobal Recycled StandardGlobal Recycled StandardGlobal Recycled Standard

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.

Fairly easy to install if you watch a tutorial on YouTube first. I would say it went well for me but still ended up having excess folds which creates small gaps for bugs, etc to possibly enter. Good quality material, I can see it surviving a long time with daily use.

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.

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.

Got this for a side opening windows for me ecoflow wave 2, works absolutely perfect. Not much in the way of insulation but can cool a 10m2 room down to 18deg C no sweat. I kept the curtain close to help

Easy and quick to install on a double glazed window that opens outwards. Instructions are straightforward - essentially, clean frames, stick on self-sticking velcro, and attach the material. Oh, I should mention that as my window is smaller than the material, I put pleats in the seal in order to absorb some lengths and to prevent a flapping overlap at the end. You'll know what I mean when/if you get one. Velcro has, so far, stayed in place though I may need to take it off the seal whilst I wait for an air-conditioner replacement - story for another review.

Avoid this company product failed after 3 months and they will not send out replacement tape.

It is extremely easy to install. Trick is to watch the videos relevant to your window, then watch them again! Assuming you've ordered the correct size, once the Velcro is on the window and the frame, if you do put it on the wrong way (yes you can!) simply pull it of and correct your mistake.As my new air con arrived a few days before I got this, I simply stuck the hose out of the bedroom window. It worked OKish, but what a difference it made after installing this! The room cools down significantly quicker and you can feel the air resistance when you open or close the bedroom door with the air con going.We've had two follow up emails since we bought this asking us to contact the supplier if we had an installation problem (not enough Velcro etc) and they would sort t out for us. Not needed thankfully but a reassuring touch.Shane I couldn't give them more than 5!!
