It should have better packaging that protects it as a material, as it gets damaged before purchase, simply from possible placement on a shelf with sunlight or if pressed by other products, it should also have a wider, better, and denser glue

I have installed it in a house on an island that has wooden windows. Apart from cutting the air, it also cuts the noise created by the air.
As others mention in the comments, you should clean the surface well before applying it.
It has a very strong adhesive, to the point that when you remove it, it also removes the color from the windows.
I placed it at about 40 meters. I was saved..

It sticks very well. It is possible that your door does not close properly and requires force to close. You will need to fix the lock to be complete.

It stuck just fine, be careful your gap needs to be at least 2-3 mm otherwise it becomes difficult to close the door.
