Fiddly to put up
It’s fiddly to put up and directions don’t tell you how to fit the corners, or how to deal with excess. I made it fit and it does the job well.

Does the job, but rough velcro side used on the window, rather than soft side
This does a good job, but the biggest issue is that they used the softer velcro on the fabric, which you remove and the rougher side of the velcro is stuck on the window, which is left there to scratch your hands and catch all the dirt and dust. If they could swap the velcro it would be perfect.

Do not buy
I've bought Aircon seals in the past but this one is by far the worst one. It came apart as soon as I fitted it - I hadn't even inserted the hose when the seams undid themselves. I had to sew it back together (as you can see in the the picture with black thread) and use super glue to hold it all together. The velcro adhesive is also not very strong and when turning the airconditioner on, the velcro's glue started melting, resulting in a big section of the seal coming off all together. Don't go for this one if you're considering it.

Find a better model
Overall it's "ok"For roof velux windows it's a bit rubbish, but does a better job at keeping the cold in, that not having it.

Adhesive not sticking
The included adhesive doesn’t stay stuck to the window.
