Product review (4 stars): Pretty darn good!
I have owned this 2 burner cooktop since 2012 and have generally enjoyed using it.  I mainly use cast iron and enameled cast iron on it and occasionally steel pots.  Temperature control is good.  The unit gets very hot and can boil 5 qts of water in a reasonable time.  It can also be used on low temperatures very successfully.

I bought this cooktop to be my main stove unit in an apartment that is without one.  It is lightweight, and easily cleaned.  I will happily take it with me for party/buffet use when I move.  I got it for what I considered to be a very reasonable price.

My only complaints that made it 4 stars instead of 5 are:
1.  When the unit is turned on by the back switch, the burners both ghost on for a few seconds even if they are both turned off.  I am, therefor, always sure to turn the unit off from the main switch when I am not using it.
2.  The burner controls themselves are easily moved out of calibration in regards to their markings and indicator.  You still have the full range of heat, but it can be difficult to tell if you are set for "1" or "1.5", etc..  I mainly pay attention to how far from the "off stop" position I have moved the knob.

I would recommend this unit.
