I am accustomed to doing root-cause failure analysis at work. I enjoy the forensic challenge of identifying new failure modes.  It is essential to work to improve quality and reliability.  When it comes to products I purchase, however, I like to think someone else has made the effort to do this. I recently purchased new studio lights and one of three did not operate properly.  Pictured above is the source of the problem (two fractured solder joints on the high-voltage capacitor).  This failure was obviously caused by mechanical trauma sustained during shipping. I sent the photo to the manufacturer and hope they will endeavor to improve their packaging or reduce the mechanical stress these joints are exposed to.  I re-soldered the connections and my light is as good as new and I did not have to wait for weeks while it shipped back and forth to the service center.
