Product review (1 stars): don't be fooled.
I had high hopes for this gas burner knob control as a replacement for the original.  I could not get it to slide on the D-shaped male part on the range.  It may look the exact same as the knob you're replacing, but the D female part on the replacement knob is smaller than the original.  I tried to slide the replacement knob on but it would not slide easily without significant force.

One aesthetic note: the lettering for all of the settings is backwards and doesn't match the original knobs at all.
