Query: Good supplemental burner

We are in process of kitchen remodel and so this replaces our stove. To be clear this is not a match for a stove burner. As with other comments, boiling can take a but longer. But so far it does a VERY good job. It is IMPORTANT to try and match a pot size diameter with the burner's. Too large and boiling can take a long time.
