Product review (1 stars): Will not heat with most cookware
This item will not work with most cookware.
The magnetic use conduction feature will not pickup Steel through a thin aluminum bottom that is on most pots and pans.

We tested it on these pots:
1: Expensive non-stick heavy gauge aluminum pots = FAIL
2: Expensive stainless steel pots with aluminum bottoms = FAIL
3: Ikea steel pot = PASS
4: Cheap, light gauge steel pot = PASS

So, if you have expensive pots and pans that happen to have aluminum bottoms, this burner is useless.
