Product review (2 stars): Very nice quality burner knobs, but not compatible.
Nice knobs but are not compatible with the stems on my stove top; waiting to hear if seller will assist.  Watch for the stem description, the knob opening appears large enough but it appears to be for a half circle stem.  My stove tops stems are flat on opposite sides (west and east) and curved on the top and bottom (north and south). My stove top stems also have a groove down the sides so the knob that may work will most likely have a raised ridge inside to "catch" the groove to assist in turning it.  So frustrating to have one appliance out last all other ones in the kitchen, yet the original knobs melted early in use when I had the cartridge for fryer on.  I never used the fryer again but sure would like to have knobs for this stove top.
