For my 130x60 cm small window I came back absolutely. Now it depends though only just under 2 months in windows, but since then no signs of peeling the adhesive underside of the Velcro under. I had to be careful when applying this thin but sticky Velcro licorice role. Thoughtlessness I put this up and let the tape roll down .. Quick curled quite apart, the liner pulled off automatically - whereby the adhesive film quickly anpappt times there where it should not. A few centimeters quickly are there times unusable because each half knotted / high adhesion and no longer can be brought apart. .. A tape measure, 4 each tailored blanks with good scissors - I would have spared this unnecessary trouble. ;)
