Query: Nice idea, but don't stick well

Bought these quick corners hoping they would speed up prep-work, but they serisously don't stick well. Sure they're for "delicate surfaces", but even on flat painted walls/ceiling that should be easy to adhear to, these corner tabs kept falling off and paint would easily slip under the edges. Save the troule and money and just use masking tape in the corner.
