That feedback ignores the basic design of the wiper mount hardness-material,
vs the wiper arm
softness material. It's designed to allow for this problem by designing the
arm attachment
to fail and NOT ruin the wiper motor or related mounting mechanism.
I don't know of any wiper arms that have a hard enough mounting material to
do any
damage to the motor mounting point. It it happens it's rare.
