Query: Flimsy

This charger is speedy and compact -- necessities for effective picture-taking.But the plug (which pivots out from the unit to plug into a wall) is flimsy. After only five months of occasional use, the pivot came loose and now the plug doesn't carry power into the charger. So I can waste time getting warranty service, or I can spend $80 for a new charger.
