Product review (4 stars): White version works fine and I'm pleased with its features
I bought the NGM5624UC model, which is white and has a 16K BTU center power burner. I deliberately did not get the stainless steel version as it seemed as waste of money for nothing extra. I am very happy with the cooktop. The simmer burner [I wish it had 2 of these] kept soup bubbling but not burning. The power burner heated a large pot of water to boiling quickly, and better yet, came right back to a boil after I added the tortellini. The variable heat settings enabled me to keep the pasta boiling but not boiling over, much better than my old cooktop with just Hi-Med-Low settings. The grates are heavy and set-in, so they're not going to shift when moving pots around. Nice feature is you turn knobs clockwise to OFF, and counterclockwise to lower the heat, so  that you can turn the knob all the way to its lowest setting without turning if off and having to relight.
