Product review (2 stars): Poor quality
Not what I expected.  This product is poor quality.  Parts don't fit together well.  The metal rings that have the temperature settings printed on them don't fit over the plastic knob so it was difficult to get them stuck together.  The colored adapters don't fit well in the plastic knob and are difficult to get over the post on the switch.  This makes the knob sit too high on the switch.
