Product review (3 stars): Be sure to get all info before you buy.
I've had this one for a few weeks, but it is still untested.  I consider two qualities to be cons:  Firstly, I was  under the impression any metal cookware would work (NOT). It has to be steel.  I found a skillet after some research.  Secondly, I thought I could set any temperature within a huge range, but it only has 5 presets.  More later.
