Product review (4 stars): Save some money
Says Thermador, but is exactly the same as the one I replaced in my Bosch 30" gas range, at less than half the price of the Bosch replacement part.  It works well until it burns itself out, usually 2 - 3 years of normal use.  This is the 3rd or 4th replacement on the same range. Seems they should last a lot longer.
