Product review (4 stars): Bosch gas cook top
After many pots burned on a smooth surface electric cook top due to heat control issues, I switched to the model 500 black four burner Bosch. My cooking skills improved drastically. Having full control of burners from the slightest simmer to a mind bending wok cooking style, this unit is amazing. Only reason it didn't rate 5 stars....it's a pain to clean due to knob placement. Cast irom grids are far superior to other manufacturers.
