Product review (5 stars): Clothes Dryer Heater Coils Restring Kit
I have purchased these a few times to repair my Dryer.  The dryer lasted me for twenty years with the exception of heater elements that usually go after regular use.  Most people will buy a new dryer not knowing how to fix the heating elements.  The restring kit cost about $12 to $15.  New dryer will cost you 20 times the cost of the repair if you can do it yourself.

I have not had any problems with it and I will recommend this to anyone DIY person....
