I'm using Magic Tape for many years and am very satisfied. It sticks almost anywhere. On plastered walls does not consider it as good. It can be removed in the first few weeks without any problems again. After three months at the window however, it is but a Pulerei. Still, I've got so far always without leaving any residue chemistry back down. At the same time it keeps super.
Stripping works by paper within about one to two hours mostly good.
The funny Katzenabroller is quite ok. It is not as suitable for everyday use in an office, because it is not as stable as a simple dispenser. But it fulfills its function and makes a nice optical impression.
