Product review (5 stars): Nice set of repair parts.
My dryer stopped working and I thought it was the belt but from other  reviews I decided to order the entire kit with the pulley and rollers.  It turned out that my belt was broken and the plastic pulley was melted.  My rollers were hardly worn but I replaced them anyway just to be safe.  The entire repair took only about 30 minutes.  Very easy do it yourself project.
