Product review (5 stars): works with thermador & bosh too!!!
Replacement grate feet for Thermador/Bosch are outrageously expensive (4 for $11-13).  These GE ones are much less expensive and I think will last longer.  They have a slightly shorter stem (by 1 mm), but the diameter is ever so slightly bigger.  I think this is an advantage, as they won't fall out so often.  I had to slightly lubricate the stem with olive oil to ease placement.  My mom has a Bosch and had the same experience.  So use these for Thermador/Bosch!!!!
