I installed it on 4 quadruple wooden windows and two wooden doors. Very easy installation and they really do a very good job. Its adhesive is not that strong, but since it stayed pressed when the doors/windows were closed, it stuck just fine.

I installed them on synthetic balcony door frames and I am satisfied. But they require some attention during installation. First, the surfaces need to be cleaned well before installation. Second, during installation they should not be stretched (to increase their length) but simply stuck as they are because stretching may cause detachment at the edges. Third, even without stretching, some edges may detach so check the next day and reattach them. After this process, they will stick forever

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 first used it on all the internal doors in 2008 and I still use it in 2022. It doesn't come off on its own, but if you make a mistake and pull it, it comes off, so don't press it too hard until you find the right position. Over the years, its height naturally "drops," but it still does the job. I am very satisfied, I won't change it.
