These cooktops are unbelievably good value for the price, as a gasfitter they are ideal for converting from electric to gas as the cut out suits most 60 cm cooktops, but you can tell just by how well they light the burners and the feel of the knobs for flame control that this is a quality product. I will be supplying and recommending this cooktop to any future customers of mine. Keep up the good work Astivita.
