So far, it holds properly, although it is a bit wrinkled (from careless packing the tent). From detaching corners I did not notice anything even after the tent again stood on several 4-day festival and was fully rained vigorously.
(TIP!) But that could be because I have the corners radiused. (TIP!)
Of course I have the repair area also cleaned very conscientious and dried, the tape then well smoothed.
Overall recommended, because you can sometimes overlook the slightly high price of 7 euros for two relatively small stickers.
