iPhone Charger

The iPhone chargers seem to be kind of weak on the connections at the plug ends.  I swear I don't abuse these things, but a few of mine are coming apart.  Good thing I have several, but figured I'd just reinforce a couple that are coming apart.  I basically reinforced with electrical tape and wrapped with string going down and back up.  Super Glued the end of the string, which dries in literally seconds.
