Product review (3 stars): it's okay, but not for us
These are nice knobs and come with a whole bunch of adapters. They even have one that fits on the controls on our Jennair cooktop. Unfortunately, the Jennair wants knobs with a distinctly different shape, so these fit, but stand up like mushrooms. We wound up putting the stick on labels from these on our old knobs whose lettering and numbering had faded, so they weren't a complete waste.
