The Siemens ET645CEA1E is a reliable ceramic cooktop without any bells or whistles. The cooktop has 4 zones, 2 are extra large and 2 are normal in size. On the large cooking zones, you can put a wok or large frying pan and on the others, there' s space for a pot of rice or potatoes. The dials are to the right side and you have the choice of 9 different settings to heat your dish. The residual heat indicators show you which zones are still warm after cooking. Cleaning the cooktop is simple because of the glass surface: simply wipe it off with a wet cloth and your cooktop is ready for next time.
