i have had a load. On my computer and cars, garage doors and windows. They are now over two years old and all are standing the test of time. No fading and no coming loose at the edges in spite of pressure washing. I can only speak for these but have found them much much better than some work
stickers that were supposed to be 7 year guaranteed adherance. Hope this helps. Dancing Pandas, Panda 40 year anniversary among others.
