Product review (5 stars): No More Dryer Drum Gap!
I ordered this to fix the gap in my dryer's drum where zippers, buttons, and strings were getting caught.  We've thrown away lots of perfectly good clothing because the gap had ruined them.  Well, this took a little bit of time to replace, but it is paying off huge dividends for us.  You'll need some time, patience, and some instructions (not provided).
