I'm considering asking Santa for a single-hob portable induction cooktop this year. I've resisted these for awhile now, because I haven't found one that seems right to me. A common limitation is that most seem to have only nine or ten power (or heat) levels, when it seems that giving finer control would cost next to nothing for a device of this type.
However I have recently noticed that the Sunpentown SR-1891B has twenty levels. This seems enough to me. Does anyone have this model? I would like to know how the quality is and whether there are any drawbacks in the way it operates.
