this samsung cooktop is a replacement of a 10 year old kitchen aid induction cooktop.  i selected this samsung model as it has the same cooking element dimensions as my previous.  i like the black background as well. 
it is easy to use and to adjust temperature.   however, it does seem to boil water a little slower than the kitchen aid.  the price is fair for an induction cooktop on the market.  i received compensation for this review, but the review is my own
