Product review (4 stars): Works fine.
I needed to get the old screws milled out and oversized holes threaded at a machine shop.  $20 to retread two burners, plus 6-32 X1/4" SS machine screws to install new igniters.  My 1998 Amana cooktop works like new again, but the crappy black setting marks for the burner knobs are all worn off.
