Hi all. I have a 'busted' MegaSafe adaptor extension cord,.... or rather, i'm not sure weather it would still work ... The centre pin of the AC plug is now gone....... Overtime, it became bent, so i just straightened it with a pair of pliers.. Now all this back and forth motion, have broken this centre pin plug... Is this extension still ok to use as I left it out, and just used the MegaSafe (as is), because I was worries i would short something. Or should i just replace the extension (if possible) ?
