Product review (5 stars): We Love it!
Due to the very low price I was a bit apprehensive about ordering this cook top. Then I decided to cover it with a service policy, figuring that if it worked for three years, it would work forever, and what the heck, everything is made in China, anyway, I decided to order it.

 It is a well made, attractive cooktop, well worth more than the Amazon price.
As others have stated it doesn't come with much in the way of documentation, and it requires 240 volts.  In the US we expect the wire to conform  to White is neutral, Black is positive and in the case of 220-240 volts a third wire which should be red. You should read 120 volts between the red and white and the black and white, while reading 220-240 between the red and black. You may have a fourth copper bare wire for a ground to prevent any stray voltage from getting loose. I connected the green on the cooktop to white and the other two colors (mine were tan and blue)  one to the black and the other to the red (I'm not sure it matters which is connected to which). It powered up just fine and now we have this really nice looking cooktop in our kitchen.
We also had to order new cookware and ordered the stainless steel set (Cook N Home) available on Amazon for a really great price and retired our old pots and pans (they were non-stick coated). After a trial or two we have learned to cook with non-stick coated cookware just like the real chefs.
By the wife and I are elderly, but we can still learn new things.
