"This is common.  I worked for Motorola for several years and recall a project where a charger for use for fire departments was in question.  Said charger was was not received well initially as it was "plastic" and cheap (mainly due to weight perception).  A quick update was made to add some metal plates internally drastically increasing its weight...magically, now it was a higher quality, with the ironic twist that now is was more apt to be damaged in a drop situation (go figure)."
