Product review (3 stars): Flame control is lacking, unit is bigger than it looks.
Overall, this unit does the job of cooking food, but it has some issues. First, the starter only works about 1/2 the time. Not a big deal, since I keep an extention lighter near by. My unit came with the cast iron burner elements covered in gold spraypaint for some reason. They smoked and stank the first few times I tried to cook with the unit. I'm guessing the fumes are not at all good for you and probably not something you want billowing up around your food. The four spoke pan supports don't offer a lot of stability to your pots and pans, especially smaller ones, 8" or less. They tend to slip off because the spokes don't extend far enough toward the center. Five or six spokes, each an inch longer, would be a significant improvement. The inner and outer ring of each element has an airflow adjuster under the glass surface. In my experience, the knobs and air adjustments don't give enough control. Even on the lowest setting, the center element has a high flame that will burn the food in the center of the pot or pan unless I turn the pressure way down at the tank regulator. Forget about a low simmer unless you are willing to monkey with the primary regulator. This unit is also bigger than it looks in the photos. The given dimensions are accurate, though, so lay out a piece of cardboard or the equivalent to get a sense of the actual scale before you order it. In retrospect, I probably could have chosen a smaller/cheaper unit and been just as satisfied.
